Underscore.js

- -

- Underscore is a - utility-belt library for JavaScript that provides a lot of the - functional programming support that you would expect in - Prototype.js - (or Ruby), - but without extending any of the built-in JavaScript objects. It's the - tie to go along with jQuery's tux. -

- -

- Underscore provides 60-odd functions that support both the usual - functional suspects: map, select, invoke — - as well as more specialized helpers: function binding, javascript - templating, deep equality testing, and so on. It delegates to built-in - functions, if present, so modern browsers will use the - native implementations of forEach, map, reduce, - filter, every, some and indexOf. -

- -

- A complete Test & Benchmark Suite - is included for your perusal. -

- -

- You may also read through the annotated source code. -

- -

- The project is - hosted on GitHub. - You can report bugs and discuss features on the - issues page, - on Freenode in the #documentcloud channel, - or send tweets to @documentcloud. -

- -

- Underscore is an open-source component of DocumentCloud. -

Object-Oriented and Functional Styles

- -

- You can use Underscore in either an object-oriented or a functional style, - depending on your preference. The following two lines of code are - identical ways to double a list of numbers. -

- -
-_.map([1, 2, 3], function(n){ return n * 2; });
-_([1, 2, 3]).map(function(n){ return n * 2; });
- -

- Using the object-oriented style allows you to chain together methods. Calling - chain on a wrapped object will cause all future method calls to - return wrapped objects as well. When you've finished the computation, - use value to retrieve the final value. Here's an example of chaining - together a map/flatten/reduce, in order to get the word count of - every word in a song. -

- -
-var lyrics = [
-  {line : 1, words : "I'm a lumberjack and I'm okay"},
-  {line : 2, words : "I sleep all night and I work all day"},
-  {line : 3, words : "He's a lumberjack and he's okay"},
-  {line : 4, words : "He sleeps all night and he works all day"}
-];
-
-_(lyrics).chain()
-  .map(function(line) { return line.words.split(' '); })
-  .flatten()
-  .reduce(function(counts, word) {
-    counts[word] = (counts[word] || 0) + 1;
-    return counts;
-}, {}).value();
-
-=> {lumberjack : 2, all : 4, night : 2 ... }
- -

- In addition, the - Array prototype's methods - are proxied through the chained Underscore object, so you can slip a - reverse or a push into your chain, and continue to - modify the array. -

- -

Collection Functions (Arrays or Objects)

- -

- each_.each(list, iterator, [context]) - Alias: forEach -
- Iterates over a list of elements, yielding each in turn to an iterator - function. The iterator is bound to the context object, if one is - passed. Each invocation of iterator is called with three arguments: - (element, index, list). If list is a JavaScript object, iterator's - arguments will be (value, key, list). Delegates to the native - forEach function if it exists. -

-
-_.each([1, 2, 3], function(num){ alert(num); });
-=> alerts each number in turn...
-_.each({one : 1, two : 2, three : 3}, function(num, key){ alert(num); });
-=> alerts each number in turn...
- -

- map_.map(list, iterator, [context]) -
- Produces a new array of values by mapping each value in list - through a transformation function (iterator). If the native map method - exists, it will be used instead. If list is a JavaScript object, - iterator's arguments will be (value, key, list). -

-
-_.map([1, 2, 3], function(num){ return num * 3; });
-=> [3, 6, 9]
-_.map({one : 1, two : 2, three : 3}, function(num, key){ return num * 3; });
-=> [3, 6, 9]
- -

- reduce_.reduce(list, iterator, memo, [context]) - Aliases: inject, foldl -
- Also known as inject and foldl, reduce boils down a - list of values into a single value. Memo is the initial state - of the reduction, and each successive step of it should be returned by - iterator. -

-
-var sum = _.reduce([1, 2, 3], function(memo, num){ return memo + num; }, 0);
-=> 6
-
- -

- reduceRight_.reduceRight(list, iterator, memo, [context]) - Alias: foldr -
- The right-associative version of reduce. Delegates to the - JavaScript 1.8 version of reduceRight, if it exists. Foldr - is not as useful in JavaScript as it would be in a language with lazy - evaluation. -

-
-var list = [[0, 1], [2, 3], [4, 5]];
-var flat = _.reduceRight(list, function(a, b) { return a.concat(b); }, []);
-=> [4, 5, 2, 3, 0, 1]
-
- -

- detect_.detect(list, iterator, [context]) -
- Looks through each value in the list, returning the first one that - passes a truth test (iterator). The function returns as - soon as it finds an acceptable element, and doesn't traverse the - entire list. -

-
-var even = _.detect([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> 2
-
- -

- select_.select(list, iterator, [context]) - Alias: filter -
- Looks through each value in the list, returning an array of all - the values that pass a truth test (iterator). Delegates to the - native filter method, if it exists. -

-
-var evens = _.select([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> [2, 4, 6]
-
- -

- reject_.reject(list, iterator, [context]) -
- Returns the values in list without the elements that the truth - test (iterator) passes. The opposite of select. -

-
-var odds = _.reject([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
-=> [1, 3, 5]
-
- -

- all_.all(list, iterator, [context]) - Alias: every -
- Returns true if all of the values in the list pass the iterator - truth test. Delegates to the native method every, if present. -

-
-_.all([true, 1, null, 'yes'], _.identity);
-=> false
-
- -

- any_.any(list, [iterator], [context]) - Alias: some -
- Returns true if any of the values in the list pass the - iterator truth test. Short-circuits and stops traversing the list - if a true element is found. Delegates to the native method some, - if present. -

-
-_.any([null, 0, 'yes', false]);
-=> true
-
- -

- include_.include(list, value) - Alias: contains -
- Returns true if the value is present in the list, using - === to test equality. Uses indexOf internally, if list - is an Array. -

-
-_.include([1, 2, 3], 3);
-=> true
-
- -

- invoke_.invoke(list, methodName, [*arguments]) -
- Calls the method named by methodName on each value in the list. - Any extra arguments passed to invoke will be forwarded on to the - method invocation. -

-
-_.invoke([[5, 1, 7], [3, 2, 1]], 'sort');
-=> [[1, 5, 7], [1, 2, 3]]
-
- -

- pluck_.pluck(list, propertyName) -
- A convenient version of what is perhaps the most common use-case for - map: extracting a list of property values. -

-
-var stooges = [{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}];
-_.pluck(stooges, 'name');
-=> ["moe", "larry", "curly"]
-
- -

- max_.max(list, [iterator], [context]) -
- Returns the maximum value in list. If iterator is passed, - it will be used on each value to generate the criterion by which the - value is ranked. -

-
-var stooges = [{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}];
-_.max(stooges, function(stooge){ return stooge.age; });
-=> {name : 'curly', age : 60};
-
- -

- min_.min(list, [iterator], [context]) -
- Returns the minimum value in list. If iterator is passed, - it will be used on each value to generate the criterion by which the - value is ranked. -

-
-var numbers = [10, 5, 100, 2, 1000];
-_.min(numbers);
-=> 2
-
- -

- sortBy_.sortBy(list, iterator, [context]) -
- Returns a sorted copy of list, ranked by the results of running - each value through iterator. -

-
-_.sortBy([1, 2, 3, 4, 5, 6], function(num){ return Math.sin(num); });
-=> [5, 4, 6, 3, 1, 2]
-
- -

- groupBy_.groupBy(list, iterator) -
- Splits a collection into sets, grouped by the result of running each - value through iterator. -

-
-_.groupBy([1.3, 2.1, 2.4], function(num){ return Math.floor(num); });
-=> {1: [1.3], 2: [2.1, 2.4]}
-
- -

- sortedIndex_.sortedIndex(list, value, [iterator]) -
- Uses a binary search to determine the index at which the value - should be inserted into the list in order to maintain the list's - sorted order. If an iterator is passed, it will be used to compute - the sort ranking of each value. -

-
-_.sortedIndex([10, 20, 30, 40, 50], 35);
-=> 3
-
- -

- toArray_.toArray(list) -
- Converts the list (anything that can be iterated over), into a - real Array. Useful for transmuting the arguments object. -

-
-(function(){ return _.toArray(arguments).slice(0); })(1, 2, 3);
-=> [1, 2, 3]
-
- -

- size_.size(list) -
- Return the number of values in the list. -

-
-_.size({one : 1, two : 2, three : 3});
-=> 3
-
- -

Array Functions

- -

- Note: All array functions will also work on the arguments object. -

- -

- first_.first(array, [n]) - Alias: head -
- Returns the first element of an array. Passing n will - return the first n elements of the array. -

-
-_.first([5, 4, 3, 2, 1]);
-=> 5
-
- -

- rest_.rest(array, [index]) - Alias: tail -
- Returns the rest of the elements in an array. Pass an index - to return the values of the array from that index onward. -

-
-_.rest([5, 4, 3, 2, 1]);
-=> [4, 3, 2, 1]
-
- -

- last_.last(array) -
- Returns the last element of an array. -

-
-_.last([5, 4, 3, 2, 1]);
-=> 1
-
- -

- compact_.compact(array) -
- Returns a copy of the array with all falsy values removed. - In JavaScript, false, null, 0, "", - undefined and NaN are all falsy. -

-
-_.compact([0, 1, false, 2, '', 3]);
-=> [1, 2, 3]
-
- -

- flatten_.flatten(array) -
- Flattens a nested array (the nesting can be to any depth). -

-
-_.flatten([1, [2], [3, [[[4]]]]]);
-=> [1, 2, 3, 4];
-
- -

- without_.without(array, [*values]) -
- Returns a copy of the array with all instances of the values - removed. === is used for the equality test. -

-
-_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);
-=> [2, 3, 4]
-
- -

- union_.union(*arrays) -
- Computes the union of the passed-in arrays: the list of unique items, - in order, that are present in one or more of the arrays. -

-
-_.union([1, 2, 3], [101, 2, 1, 10], [2, 1]);
-=> [1, 2, 3, 101, 10]
-
- -

- intersection_.intersection(*arrays) -
- Computes the list of values that are the intersection of all the arrays. - Each value in the result is present in each of the arrays. -

-
-_.intersection([1, 2, 3], [101, 2, 1, 10], [2, 1]);
-=> [1, 2]
-
- -

- difference_.difference(array, other) -
- Similar to without, but returns the values from array that - are not present in other. -

-
-_.difference([1, 2, 3, 4, 5], [5, 2, 10]);
-=> [1, 3, 4]
-
- -

- uniq_.uniq(array, [isSorted]) - Alias: unique -
- Produces a duplicate-free version of the array, using === to test - object equality. If you know in advance that the array is sorted, - passing true for isSorted will run a much faster algorithm. -

-
-_.uniq([1, 2, 1, 3, 1, 4]);
-=> [1, 2, 3, 4]
-
- -

- zip_.zip(*arrays) -
- Merges together the values of each of the arrays with the - values at the corresponding position. Useful when you have separate - data sources that are coordinated through matching array indexes. - If you're working with a matrix of nested arrays, zip.apply - can transpose the matrix in a similar fashion. -

-
-_.zip(['moe', 'larry', 'curly'], [30, 40, 50], [true, false, false]);
-=> [["moe", 30, true], ["larry", 40, false], ["curly", 50, false]]
-
- -

- indexOf_.indexOf(array, value, [isSorted]) -
- Returns the index at which value can be found in the array, - or -1 if value is not present in the array. Uses the native - indexOf function unless it's missing. If you're working with a - large array, and you know that the array is already sorted, pass true - for isSorted to use a faster binary search. -

-
-_.indexOf([1, 2, 3], 2);
-=> 1
-
- -

- lastIndexOf_.lastIndexOf(array, value) -
- Returns the index of the last occurrence of value in the array, - or -1 if value is not present. Uses the native lastIndexOf - function if possible. -

-
-_.lastIndexOf([1, 2, 3, 1, 2, 3], 2);
-=> 4
-
- -

- range_.range([start], stop, [step]) -
- A function to create flexibly-numbered lists of integers, handy for - each and map loops. start, if omitted, defaults - to 0; step defaults to 1. Returns a list of integers - from start to stop, incremented (or decremented) by step, - exclusive. -

-
-_.range(10);
-=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
-_.range(1, 11);
-=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
-_.range(0, 30, 5);
-=> [0, 5, 10, 15, 20, 25]
-_.range(0, -10, -1);
-=> [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]
-_.range(0);
-=> []
-
- -

Function (uh, ahem) Functions

- -

- bind_.bind(function, object, [*arguments]) -
- Bind a function to an object, meaning that whenever - the function is called, the value of this will be the object. - Optionally, bind arguments to the function to pre-fill them, - also known as currying. -

-
-var func = function(greeting){ return greeting + ': ' + this.name };
-func = _.bind(func, {name : 'moe'}, 'hi');
-func();
-=> 'hi: moe'
-
- -

- bindAll_.bindAll(object, [*methodNames]) -
- Binds a number of methods on the object, specified by - methodNames, to be run in the context of that object whenever they - are invoked. Very handy for binding functions that are going to be used - as event handlers, which would otherwise be invoked with a fairly useless - this. If no methodNames are provided, all of the object's - function properties will be bound to it. -

-
-var buttonView = {
-  label   : 'underscore',
-  onClick : function(){ alert('clicked: ' + this.label); },
-  onHover : function(){ console.log('hovering: ' + this.label); }
-};
-_.bindAll(buttonView);
-jQuery('#underscore_button').bind('click', buttonView.onClick);
-=> When the button is clicked, this.label will have the correct value...
-
- -

- memoize_.memoize(function, [hashFunction]) -
- Memoizes a given function by caching the computed result. Useful - for speeding up slow-running computations. If passed an optional - hashFunction, it will be used to compute the hash key for storing - the result, based on the arguments to the original function. The default - hashFunction just uses the first argument to the memoized function - as the key. -

-
-var fibonacci = function(n) {
-  return n < 2 ? n : fibonacci(n - 1) + fibonacci(n - 2);
-};
-var fastFibonacci = _.memoize(fibonacci);
-
- -

- delay_.delay(function, wait, [*arguments]) -
- Much like setTimeout, invokes function after wait - milliseconds. If you pass the optional arguments, they will be - forwarded on to the function when it is invoked. -

-
-var log = _.bind(console.log, console);
-_.delay(log, 1000, 'logged later');
-=> 'logged later' // Appears after one second.
-
- -

- defer_.defer(function) -
- Defers invoking the function until the current call stack has cleared, - similar to using setTimeout with a delay of 0. Useful for performing - expensive computations or HTML rendering in chunks without blocking the UI thread - from updating. -

-
-_.defer(function(){ alert('deferred'); });
-// Returns from the function before the alert runs.
-
- -

- throttle_.throttle(function, wait) -
- Returns a throttled version of the function, that, when invoked repeatedly, - will only actually call the wrapped function at most once per every wait - milliseconds. Useful for rate-limiting events that occur faster than you - can keep up with. -

-
-var throttled = _.throttle(updatePosition, 100);
-$(window).scroll(throttled);
-
- -

- debounce_.debounce(function, wait) -
- Repeated calls to a debounced function will postpone it's execution - until after wait milliseconds have elapsed. Useful for implementing - behavior that should only happen after the input has stopped arriving. - For example: rendering a preview of a Markdown comment, recalculating a - layout after the window has stopped being resized... -

-
-var lazyLayout = _.debounce(calculateLayout, 300);
-$(window).resize(lazyLayout);
-
- -

- once_.once(function) -
- Creates a version of the function that can only be called one time. - Repeated calls to the modified function will have no effect, returning - the value from the original call. Useful for initialization functions, - instead of having to set a boolean flag and then check it later. -

-
-var initialize = _.once(createApplication);
-initialize();
-initialize();
-// Application is only created once.
-
- -

- after_.after(count, function) -
- Creates a version of the function that will only be run after first - being called count times. Useful for grouping asynchronous responses, - where you want to be sure that all the async calls have finished, before - proceeding. -

-
-var renderNotes = _.after(notes.length, render);
-_.each(notes, function(note) {
-  note.asyncSave({success: renderNotes}); 
-});
-// renderNotes is run once, after all notes have saved.
-
- -

- wrap_.wrap(function, wrapper) -
- Wraps the first function inside of the wrapper function, - passing it as the first argument. This allows the wrapper to - execute code before and after the function runs, adjust the arguments, - and execute it conditionally. -

-
-var hello = function(name) { return "hello: " + name; };
-hello = _.wrap(hello, function(func) {
-  return "before, " + func("moe") + ", after";
-});
-hello();
-=> 'before, hello: moe, after'
-
- -

- compose_.compose(*functions) -
- Returns the composition of a list of functions, where each function - consumes the return value of the function that follows. In math terms, - composing the functions f(), g(), and h() produces - f(g(h())). -

-
-var greet    = function(name){ return "hi: " + name; };
-var exclaim  = function(statement){ return statement + "!"; };
-var welcome = _.compose(exclaim, greet);
-welcome('moe');
-=> 'hi: moe!'
-
- -

Object Functions

- -

- keys_.keys(object) -
- Retrieve all the names of the object's properties. -

-
-_.keys({one : 1, two : 2, three : 3});
-=> ["one", "two", "three"]
-
- -

- values_.values(object) -
- Return all of the values of the object's properties. -

-
-_.values({one : 1, two : 2, three : 3});
-=> [1, 2, 3]
-
- -

- functions_.functions(object) - Alias: methods -
- Returns a sorted list of the names of every method in an object — - that is to say, the name of every function property of the object. -

-
-_.functions(_);
-=> ["all", "any", "bind", "bindAll", "clone", "compact", "compose" ...
-
- -

- extend_.extend(destination, *sources) -
- Copy all of the properties in the source objects over to the - destination object. It's in-order, to the last source will override - properties of the same name in previous arguments. -

-
-_.extend({name : 'moe'}, {age : 50});
-=> {name : 'moe', age : 50}
-
- -

- defaults_.defaults(object, *defaults) -
- Fill in missing properties in object with default values from the - defaults objects. As soon as the property is filled, further defaults - will have no effect. -

-
-var iceCream = {flavor : "chocolate"};
-_.defaults(iceCream, {flavor : "vanilla", sprinkles : "lots"});
-=> {flavor : "chocolate", sprinkles : "lots"}
-
- -

- clone_.clone(object) -
- Create a shallow-copied clone of the object. Any nested objects - or arrays will be copied by reference, not duplicated. -

-
-_.clone({name : 'moe'});
-=> {name : 'moe'};
-
- -

- tap_.tap(object, interceptor) -
- Invokes interceptor with the object, and then returns object. - The primary purpose of this method is to "tap into" a method chain, in order to perform operations on intermediate results within the chain. -

-
-_([1,2,3,200]).chain().

Utility Functions

- -

- noConflict_.noConflict() -
- Give control of the "_" variable back to its previous owner. Returns - a reference to the Underscore object. -

-
-var underscore = _.noConflict();
- -

- identity_.identity(value) -
- Returns the same value that is used as the argument. In math: - f(x) = x
- This function looks useless, but is used throughout Underscore as - a default iterator. -

-
-var moe = {name : 'moe'};
-moe === _.identity(moe);
-=> true
- -

- times_.times(n, iterator) -
- Invokes the given iterator function n times. -

-
-_(3).times(function(){ genie.grantWish(); });
- -

- mixin_.mixin(object) -
- Allows you to extend Underscore with your own utility functions. Pass - a hash of {name: function} definitions to have your functions - added to the Underscore object, as well as the OOP wrapper. -

-
-_.mixin({
-  capitalize : function(string) {
-    return string.charAt(0).toUpperCase() + string.substring(1).toLowerCase();
-  }
-});
-_("fabio").capitalize();
-=> "Fabio"
-
- -

- uniqueId_.uniqueId([prefix]) -
- Generate a globally-unique id for client-side models or DOM elements - that need one. If prefix is passed, the id will be appended to it. -

-
-_.uniqueId('contact_');
-=> 'contact_104'
- -

- template_.template(templateString, [context]) -
- Compiles JavaScript templates into functions that can be evaluated - for rendering. Useful for rendering complicated bits of HTML from JSON - data sources. Template functions can both interpolate variables, using
- <%= … %>, as well as execute arbitrary JavaScript code, with - <% … %>. When you evaluate a template function, pass in a - context object that has properties corresponding to the template's free - variables. If you're writing a one-off, you can pass the context - object as the second parameter to template in order to render - immediately instead of returning a template function. -

-
-var compiled = _.template("hello: <%= name %>");
-compiled({name : 'moe'});
-=> "hello: moe"
-
-var list = "<% _.each(people, function(name) { %> <li><%= name %></li> <% }); %>";
-_.template(list, {people : ['moe', 'curly', 'larry']});
-=> "<li>moe</li><li>curly</li><li>larry</li>"
- -

- You can also use print from within JavaScript code. This is - sometimes more convenient than using <%= ... %>. -

- -
-var compiled = _.template("<% print('Hello ' + epithet); %>");
-compiled({epithet: "stooge"});
-=> "Hello stooge."
- -

- If ERB-style delimiters aren't your cup of tea, you can change Underscore's - template settings to use different symbols to set off interpolated code. - Define an interpolate regex, and an (optional) evaluate regex - to match expressions that should be inserted and evaluated, respectively. - If no evaluate regex is provided, your templates will only be - capable of interpolating values. - For example, to perform - Mustache.js - style templating: -

- -
-_.templateSettings = {
-  interpolate : /\{\{(.+?)\}\}/g
-};
-
-var template = _.template("Hello {{ name }}!");
-template({name : "Mustache"});
-=> "Hello Mustache!"
- -

Chaining

- -

- chain_(obj).chain() -
- Returns a wrapped object. Calling methods on this object will continue - to return wrapped objects until value is used. ( - A more realistic example.) -

-
-var stooges = [{name : 'curly', age : 25}, {name : 'moe', age : 21}, {name : 'larry', age : 23}];
-var youngest = _(stooges).chain()
-  .sortBy(function(stooge){ return stooge.age; })
-  .map(function(stooge){ return stooge.name + ' is ' + stooge.age; })
-  .first()
-  .value();
-=> "moe is 21"
-
- -

- value_(obj).value() -
- Extracts the value of a wrapped object. -

-
-_([1, 2, 3]).value();
-=> [1, 2, 3]
-
- -

Duck Typing

- -

- The isType (isArray, isFunction, isString ...) family of type-checking - functions use property detection to do their work, which, although - orders of magnitude faster than the alternative, isn't entirely safe when dealing - with objects that are used as hashes, where arbitrary strings are being - set for the keys. It's entirely possible for an object to masquerade as - another type, if you're setting properties with names like "concat" and - "charCodeAt". So be aware. -

Change Log

- -

- 1.1.7July 13, 2011
- Added _.groupBy, which aggregates a collection into groups of like items. - Added _.untion and _.difference, to complement the - (re-named) _.intersection. - Various improvements for support of sparse arrays. - _.toArray now returns a clone, if directly passed an array. - _.functions now also returns the names of functions that are present - in the prototype chain. -

- -

- 1.1.6April 18, 2011
- Added _.after, which will return a function that only runs after - first being called a specified number of times. - _.invoke can now take a direct function reference. - _.every now requires an iterator function to be passed, which - mirrors the ECMA5 API. - _.extend no longer copies keys when the value is undefined. - _.bind now errors when trying to bind an undefined value. -

- -

- 1.1.5Mar 20, 2011
- Added an _.defaults function, for use merging together JS objects - representing default options. - Added an _.once function, for manufacturing functions that should - only ever execute a single time. - _.bind now delegates to the native ECMAScript 5 version, - where available. - _.keys now throws an error when used on non-Object values, as in - ECMAScript 5. - Fixed a bug with _.keys when used over sparse arrays. -

- -

- 1.1.4Jan 9, 2011
- Improved compliance with ES5's Array methods when passing null - as a value. _.wrap now correctly sets this for the - wrapped function. _.indexOf now takes an optional flag for - finding the insertion index in an array that is guaranteed to already - be sorted. Avoiding the use of .callee, to allow _.isArray - to work properly in ES5's strict mode. -

- -

- 1.1.3Dec 1, 2010
- In CommonJS, Underscore may now be required with just:
- var _ = require("underscore"). - Added _.throttle and _.debounce functions. - Removed _.breakLoop, in favor of an ECMA5-style un-break-able - each implementation — this removes the try/catch, and you'll now have - better stack traces for exceptions that are thrown within an Underscore iterator. - Improved the isType family of functions for better interoperability - with Internet Explorer host objects. - _.template now correctly escapes backslashes in templates. - Improved _.reduce compatibility with the ECMA5 version: - if you don't pass an initial value, the first item in the collection is used. - _.each no longer returns the iterated collection, for improved - consistency with ES5's forEach. -

- -

- 1.1.2
- Fixed _.contains, which was mistakenly pointing at - _.intersect instead of _.include, like it should - have been. Added _.unique as an alias for _.uniq. -

- -

- 1.1.1
- Improved the speed of _.template, and its handling of multiline - interpolations. Ryan Tenney contributed optimizations to many Underscore - functions. An annotated version of the source code is now available. -

- -

- 1.1.0
- The method signature of _.reduce has been changed to match - the ECMAScript 5 signature, instead of the Ruby/Prototype.js version. - This is a backwards-incompatible change. _.template may now be - called with no arguments, and preserves whitespace. _.contains - is a new alias for _.include. -

- -

- 1.0.4
- Andri Möll contributed the _.memoize - function, which can be used to speed up expensive repeated computations - by caching the results. -

- -

- 1.0.3
- Patch that makes _.isEqual return false if any property - of the compared object has a NaN value. Technically the correct - thing to do, but of questionable semantics. Watch out for NaN comparisons. -

- -

- 1.0.2
- Fixes _.isArguments in recent versions of Opera, which have - arguments objects as real Arrays. -

- -

- 1.0.1
- Bugfix for _.isEqual, when comparing two objects with the same - number of undefined keys, but with different names. -

- -

- 1.0.0
- Things have been stable for many months now, so Underscore is now - considered to be out of beta, at 1.0. Improvements since 0.6 - include _.isBoolean, and the ability to have _.extend - take multiple source objects. -

- -

- 0.6.0
- Major release. Incorporates a number of - Mile Frawley's refactors for - safer duck-typing on collection functions, and cleaner internals. A new - _.mixin method that allows you to extend Underscore with utility - functions of your own. Added _.times, which works the same as in - Ruby or Prototype.js. Native support for ECMAScript 5's Array.isArray, - and Object.keys. -

- -

- 0.5.8
- Fixed Underscore's collection functions to work on - NodeLists and - HTMLCollections - once more, thanks to - Justin Tulloss. -

- -

- 0.5.7
- A safer implementation of _.isArguments, and a - faster _.isNumber,
thanks to - Jed Schmidt. -

- -

- 0.5.6
- Customizable delimiters for _.template, contributed by - Noah Sloan. -

- -

- 0.5.5
- Fix for a bug in MobileSafari's OOP-wrapper, with the arguments object. -

- -

- 0.5.4
- Fix for multiple single quotes within a template string for - _.template. See: - Rick Strahl's blog post. -

- -

- 0.5.2
- New implementations of isArray, isDate, isFunction, - isNumber, isRegExp, and isString, thanks to - a suggestion from - Robert Kieffer. - Instead of doing Object#toString - comparisons, they now check for expected properties, which is less safe, - but more than an order of magnitude faster. Most other Underscore - functions saw minor speed improvements as a result. - Evgeniy Dolzhenko - contributed _.tap, - similar to Ruby 1.9's, - which is handy for injecting side effects (like logging) into chained calls. -

- -

- 0.5.1
- Added an _.isArguments function. Lots of little safety checks - and optimizations contributed by - Noah Sloan and - Andri Möll. -

- -

- 0.5.0
- [API Changes] _.bindAll now takes the context object as - its first parameter. If no method names are passed, all of the context - object's methods are bound to it, enabling chaining and easier binding. - _.functions now takes a single argument and returns the names - of its Function properties. Calling _.functions(_) will get you - the previous behavior. - Added _.isRegExp so that isEqual can now test for RegExp equality. - All of the "is" functions have been shrunk down into a single definition. - Karl Guertin contributed patches. -

- -

- 0.4.7
- Added isDate, isNaN, and isNull, for completeness. - Optimizations for isEqual when checking equality between Arrays - or Dates. _.keys is now 25%–2X faster (depending on your - browser) which speeds up the functions that rely on it, such as _.each. -

- -

- 0.4.6
- Added the range function, a port of the - Python - function of the same name, for generating flexibly-numbered lists - of integers. Original patch contributed by - Kirill Ishanov. -

- -

- 0.4.5
- Added rest for Arrays and arguments objects, and aliased - first as head, and rest as tail, - thanks to Luke Sutton's patches. - Added tests ensuring that all Underscore Array functions also work on - arguments objects. -

- -

- 0.4.4
- Added isString, and isNumber, for consistency. Fixed - _.isEqual(NaN, NaN) to return true (which is debatable). -

- -

- 0.4.3
- Started using the native StopIteration object in browsers that support it. - Fixed Underscore setup for CommonJS environments. -

- -

- 0.4.2
- Renamed the unwrapping function to value, for clarity. -

- -

- 0.4.1
- Chained Underscore objects now support the Array prototype methods, so - that you can perform the full range of operations on a wrapped array - without having to break your chain. Added a breakLoop method - to break in the middle of any Underscore iteration. Added an - isEmpty function that works on arrays and objects. -

- -

- 0.4.0
- All Underscore functions can now be called in an object-oriented style, - like so: _([1, 2, 3]).map(...);. Original patch provided by - Marc-André Cournoyer. - Wrapped objects can be chained through multiple - method invocations. A functions method - was added, providing a sorted list of all the functions in Underscore. -

- -

- 0.3.3
- Added the JavaScript 1.8 function reduceRight. Aliased it - as foldr, and aliased reduce as foldl. -

- -

- 0.3.2
- Now runs on stock Rhino - interpreters with: load("underscore.js"). - Added identity as a utility function. -

- -

- 0.3.1
- All iterators are now passed in the original collection as their third - argument, the same as JavaScript 1.6's forEach. Iterating over - objects is now called with (value, key, collection), for details - see _.each. -

- -

- 0.3.0
- Added Dmitry Baranovskiy's - comprehensive optimizations, merged in - Kris Kowal's patches to make Underscore - CommonJS and - Narwhal compliant. -

- -

- 0.2.0
- Added compose and lastIndexOf, renamed inject to - reduce, added aliases for inject, filter, - every, some, and forEach. -

- -

- 0.1.1
- Added noConflict, so that the "Underscore" object can be assigned to - other variables. -

- -

- 0.1.0
- Initial release of Underscore.js. -
