The iteratee is invoked with three arguments: (value, key, object). : __t) + '! Checks if value is the language type of Object. (boolean): Returns true if value is undefined, else false. If only one argument is provided a number between 0 and the given number is returned. The iteratees are invoked with one argument: (value). This method is like _.clone except that it recursively clones value. 最初の要素が最後に、2番目の要素が最後から2番目となるように配列を反転します。, Lodashの _.reverse は Array#reverse を呼びだして _.map(arrays, _.reverse) のような構成を利用可能にするためだけのものです。 (string): Returns the snake cased string. Creates a lodash object which wraps value to enable implicit method chain sequences. Functions and DOM nodes are compared by strict equality, i.e. Data properties may be accessed as free variables in the template. Elements are taken until predicate returns falsey. // Invoke `renewToken` when the click event is fired, but not more than once every 5 minutes. Gets n random elements at unique keys from collection up to the size of collection. Creates an array of unique values that are included in all given arrays using SameValueZero for equality comparisons. The iteratee is invoked with one argument: (value). Removes the property at path of object.Note: This method mutates object. Attempts to invoke func, returning either the result or the caught error object. Object objects are compared by their own, not inherited, enumerable properties. // Sort by `user` in ascending order and by `age` in descending order. (Function): Returns the new memoized function. (*): Returns the result of the invoked method. Checks if value is likely an arguments object. To avoid this behavior use _.forIn or _.forOwn for object iteration. (Function): Returns the new invoker function. (string): Returns the kebab cased string. --- jdalton, これは代替の実装であることに注意してください。 This method is like _.uniq except that it's designed and optimized for sorted arrays. Lodash is inspired by Underscore.js, but nowadays it is a superior solution. なぜlodash.eachはネイティブforEachよりも速いのですか? Executes the chain sequence and returns the wrapped result. // Use the internal `print` function in "evaluate" delimiters. // => `createApplication` is invoked once. This method is like _.set except that it accepts customizer which is invoked to produce the objects of path. Iterates over elements of collection and invokes iteratee for each element. If floating is true, or either lower or upper are floats, a floating-point number is returned instead of an integer.Note: JavaScript follows the IEEE-754 standard for resolving floating-point values which can produce unexpected results. Assigns own and inherited enumerable string keyed properties of source objects to the destination object for all destination properties that resolve to undefined. // => Logs 'c', 'b', then 'a' assuming `_.forIn` logs 'a', 'b', then 'c'. If radix is undefined or 0, a radix of 10 is used unless value is a hexadecimal, in which case a radix of 16 is used.Note: This method aligns with the ES5 implementation of parseInt. Checks if value is classified as a Function object. // => { '3': ['one', 'two'], '5': ['three'] }, // => { 'a': { 'dir': 'left', 'code': 97 }, 'd': { 'dir': 'right', 'code': 100 } }, // => { 'left': { 'dir': 'left', 'code': 97 }, 'right': { 'dir': 'right', 'code': 100 } }, // => [16, 64] (iteration order is not guaranteed). (boolean): Returns true if string ends with target, else false. The opposite of _.property; this method creates a function that returns the value at a given path of object. Array and plain object properties are merged recursively. This method is like _.partial except that partially applied arguments are appended to the arguments it receives.The _.partialRight.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments.Note: This method doesn't set the "length" property of partially applied functions. Similarly, maps and sets are considered empty if they have a size of 0. Creates an array of shuffled values, using a version of the Fisher-Yates shuffle. Once a property is set, additional values of the same property are ignored.Note: This method mutates object. This is a post on the lodash method _.join, as well as the corresponding Array.prototype.join method that is being referenced. Converts string, as a whole, to upper case just like String#toUpperCase. (Array): Returns the new array of regrouped elements. Creates an object composed of keys generated from the results of running each element of collection thru iteratee. build-your-own-angularの著者Tero Parviainen氏, これは認めざるを得ない。僕は#lodash乱用の罪を犯してきた。良いリソースだね。 Lodash Find vs Lodash Filter boils down to whether or not you need more than one result. O que eu The customizer is invoked with six arguments:(objValue, srcValue, key, object, source, stack).Note: This method mutates object. Creates a function that iterates over pairs and invokes the corresponding function of the first predicate to return truthy. Creates a function that checks if any of the predicates return truthy when invoked with the arguments it receives. 意訳が含まれるため、誤りやより良い表現などがあればご指摘頂けると助かります。, 原文：https://github.com/cht8687/You-Dont-Need-Lodash-Underscore, LodashとUnderscoreは素晴らしいモダンなJavaScriptユーティリティライブラリであり、フロントエンド開発者に広く使われています。しかしながら、モダンブラウザがターゲットとなる場合、ES5やES6のおかげでネイティブにサポートされたメソッドが多くあることに気づくでしょう。プロジェクトの依存関係を減らし、ターゲットブラウザが明確になっているのであれば、LodashとUnderscoreは必要ないかも知れません。, ** ES5メソッドでレガシーJavaScriptエンジンをターゲットに含めるのであれば、es5-shimを使うと良いでしょう。 See Mathias Bynens's article (under "semi-related fun fact") for more details.When working with HTML you should always quote attribute values to reduce XSS vectors. As the result of the article in jsperf.com (2015) shows that, Lodash performances faster than Native Javascript. The customizer is invoked with up to six arguments: (objValue, othValue [, index|key, object, other, stack]). This method is like _.uniqBy except that it's designed and optimized for sorted arrays. // latest 3.7.0 var _ = require (' lodash '); /** * lodash（Underscore.js） の便利な関数ライブラリたち * 「_」というオブジェクトを使用することにより利用可能 * 配列、オブジェクト操作を便利にするもの * * よく使うのは以下 * each * find * filter * where * findWhere * contains * pluck * … isNaN (NaN)); // output: true MDN: グローバルの isNaN() 関数と較べて、 Number.isNaN() はパラメータを数値に強制的に変換する問題に悩むことはあ … Removes all given values from array using SameValueZero for equality comparisons.Note: Unlike _.without, this method mutates array. log (isNaN (NaN)); // output: true // ES6 console. //   __p += 'hi ' + ((__t = ( data.user )) == null ? '' The predicate is invoked with three arguments: (value, index|key, collection). This method is like _.update except that it accepts customizer which is invoked to produce the objects of path. The order and references of result values are determined by the first array.Note: Unlike _.pullAll, this method returns a new array. (RegExp): Used to detect code to be evaluated. Lodash.js vs Native Remove Duplicates (version: 0) Comparing performance of: Native vs Lodash.js filter Created: 2 days ago by: Guest Jump to the latest result Checks if value is a safe integer. Creates a slice of array with n elements dropped from the beginning. Arrays are created for missing index properties while objects are created for all other missing properties. Iteratee functions may exit iteration early by explicitly returning false. Checks if value is a pristine native function.Note: This method can't reliably detect native functions in the presence of the core-js package because core-js circumvents this kind of detection. Performs a partial deep comparison between object and source to determine if object contains equivalent property values.Note: This method is equivalent to _.matches when source is partially applied.Partial comparisons will match empty array and empty object source values against any array or object value, respectively. Creates an object with the same keys as object and values generated by running each own enumerable string keyed property of object thru iteratee. // => Logs 'a', 'b', then 'c' (iteration order is not guaranteed). The inverse of _.escape; this method converts the HTML entities &amp;, &lt;, &gt;, &quot;, and &#39; in string to their corresponding characters.Note: No other HTML entities are unescaped. If a setting object is given, it takes precedence over _.templateSettings values.Note: In the development build _.template utilizes sourceURLs for easier debugging.For more information on precompiling templates see lodash's custom builds documentation.For more information on Chrome extension sandboxes see Chrome's extensions documentation. (boolean): Returns true if value is a number, else false. Provide options to indicate whether func should be invoked on the leading and/or trailing edge of the wait timeout. RAW Paste Data Chrome 30.0.1599.69 32-bit on Windows 8 64-bit Sit back and relax, this may take a while. (boolean): Returns true if value is less than other, else false. Performance will be calculated using the native JavaScript performance API. (boolean): Returns true if value is an error object, else false. '<% jq.each(users, function(user) { %>

The iteratee is invoked with four arguments:(accumulator, value, index|key, collection).Many lodash methods are guarded to work as iteratees for methods like _.reduce, _.reduceRight, and _.transform.The guarded methods are:assign, defaults, defaultsDeep, includes, merge, orderBy, and sortBy. If we’re using a modern browser, we can also use find, some, every and reduceRighttoo. Creates an object composed of the object properties predicate returns truthy for. Creates an array of function property names from own and inherited enumerable properties of object. (Function): Returns the new throttled function. Checks if value is a plain object, that is, an object created by the Object constructor or one with a [[Prototype]] of null. Creates an array with all falsey values removed. This method is like _.fromPairs except that it accepts two arrays, one of property identifiers and one of corresponding values. Gets the timestamp of the number of milliseconds that have elapsed since the Unix epoch (1 January 1970 00:00:00 UTC). This method is like _.find except that it iterates over elements of collection from right to left. (Array): Returns the new array of grouped elements. Removes trailing whitespace or specified characters from string. If customizer returns undefined, assignment is handled by the method instead. Because performance really matters for a good user experience, and lodash is an outsider here. Creates an object composed of the inverted keys and values of object. The opposite of _.method; this method creates a function that invokes the method at a given path of object. Iteratee functions may exit iteration early by explicitly returning false. (boolean): Returns true if value is a string, else false. (boolean): Returns true if value is a date object, else false. See the ES spec for more details. UnderscoreとLodashという2つのJavaScriptライブラリが，ひとつのプロジェクトに統合する方法についての議論を開始した。 If object is a map or set, its entries are returned. // => objects for ['barney', 'fred', 'pebbles'], // => [{ 'x': 1, 'y': 2 }, { 'x': 5, 'y': 6 }], // => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 1 }], // => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }], // => [['a', 'b'], [1, 2], [true, false]], // => [{ 'x': 2, 'y': 1 }, { 'x': 1, 'y': 1 }], // => { 'a': { 'b': [{ 'c': 1 }, { 'd': 2 }] } }. If null safety is critical for your application, we suggest that you take extra Array (boolean): Returns true if path exists, else false. This method is like _.indexOf except that it iterates over elements of array from right to left. Iterates over own enumerable string keyed properties of an object and invokes iteratee for each property. (Object): By default, the template delimiters used by lodash are like those in embedded Ruby (ERB) as well as ES2015 template strings. (Object): Returns the new lodash wrapper instance. それは前もって Underscore のようにチェーン構文中でのみ晒されるため、 _ 上に晒されます。 A value is object-like if it's not null and has a typeof result of "object". Padding characters are truncated if they exceed length. This method is like _.isMatch except that it accepts customizer which is invoked to compare values. (Array): Returns the array of property values. The customizer is invoked with five arguments: (objValue, srcValue, index|key, object, source). This method is like _.uniq except that it accepts comparator which is invoked to compare elements of array. Computes the minimum value of array. The order of result values is determined by the order they occur in the array. (boolean): Returns true if value is an arguments object, else false. Gets the size of collection by returning its length for array-like values or the number of own enumerable string keyed properties for objects. The func is invoked with the this binding of the memoized function.Note: The cache is exposed as the cache property on the memoized function. The predicate is invoked with three arguments: (value, index|key, collection).Note: This method returns true for empty collections because everything is true of elements of empty collections. Performs a SameValueZero comparison between two values to determine if they are equivalent. Assigns own enumerable string keyed properties of source objects to the destination object. The iteratee is invoked with one argument: (value). Creates a function that accepts up to one argument, ignoring any additional arguments. (*): Returns the matched element, else undefined. // => [{ 'user': 'barney', 'age': 36, 'active': true }]. The order and references of result values are determined by the first array. (Function): Returns the new capped function. This method is like _.forOwn except that it iterates over properties of object in the opposite order. Creates an object that inherits from the prototype object. The customizer is invoked with three arguments: (nsValue, key, nsObject).Note: This method mutates object. See Peter Michaux's article for more details.The _.bindKey.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments. Truncates string if it's longer than the given maximum string length. (*): Returns the resolved unwrapped value. Sections of a chain sequence qualify for shortcut fusion if the section is applied to an array and iteratees accept only one argument. This method is the wrapper version of _.at. // Use the "evaluate" delimiter to execute JavaScript and generate HTML. If a properties object is given, its own enumerable string keyed properties are assigned to the created object. (number): Returns the rounded down number. // Use the `imports` option to import `jQuery` as `jq`. The corresponding value of each key is the number of times the key was returned by iteratee. (boolean): Returns true if value is greater than other, else false. // Avoid excessively updating the position while scrolling. Creates a slice of array excluding elements dropped from the end. Converts value to an integer.Note: This method is loosely based on ToInteger. Creates a slice of array with n elements taken from the beginning. ** 下記の事例は特定のタスクを実行するネイティブの代替手段を示していることに注意してください。Lodashのいくつかの関数は、ネイティブの組み込み関数よりも多くのオプションを提供します。このリストは一対の比較ではありません。, 大げさにする前にネイティブJavaScriptのオブジェクトおよび配列ユーティリティを活用するといいよ。 To calculate the time difference, we will use the built-in Date constructor. The predicate is invoked with three arguments: (value, index, array). (Array): Returns the new duplicate free array. Subsequent calls to the created function return the result of the last func invocation. The iteratee is invoked with one argument: (value). Creates a flattened array of values by running each element in collection thru iteratee and flattening the mapped results. (boolean): Returns true if the values are equivalent, else false. Actuellement,Lodashc’est : 1. (boolean): Returns true if value is found, else false. コンピュータ科学者であり、JavaScript Ninjaの極意 ライブラリ開発のための知識とコーディングのテクニカルレビュアーでもあるDaniel Lamb氏, そうかも知れないけど、僕には必要かな。 Compare Lodash with the biggest competitors in the Libraries and Widgets market like JQuery UI OpenSSL etc. This method is like _.assignIn except that it accepts customizer which is invoked to produce the assigned values. @qiansen1386 Can't comment on "Ramda vs Lodash" (I am familiar with Lodash, but not so much with Ramda), but in Haskell (FP beast) I see it is common to use fn composition and actually prefer it even thought there are possibilities (in std. The order and references of result values are determined by the first array. If accumulator is not provided, a new object with the same [[Prototype]] will be used. This method is like _.sortedIndex except that it returns the highest index at which value should be inserted into array in order to maintain its sort order. The customizer is invoked with up to four arguments; (value [, index|key, object, stack]). GitHub Gist: instantly share code, notes, and snippets. (Array): Returns the new array of intersecting values. (Array): Returns the new array of combined values. (boolean): Returns true if number is in the range, else false. Provide options to indicate whether func should be invoked on the leading and/or trailing edge of the wait timeout. Generates a unique ID. Creates a function that invokes the method at path of a given object. Its creation may be customized by replacing the _.memoize.Cache constructor with one whose instances implement the Map method interface of clear, delete, get, has, and set. This experiment is designed to find out the performance and resource usage of map functions of both ES6 and Lodash As the result of the article in … Creates an array of elements split into groups the length of size. (boolean): Returns true if value is a typed array, else false. The order and references of result values are determined by the first array. The iteratee is invoked with three arguments:(value, index|key, collection).Many lodash methods are guarded to work as iteratees for methods like _.every, _.filter, _.map, _.mapValues, _.reject, and _.some.The guarded methods are:ary, chunk, curry, curryRight, drop, dropRight, every, fill, invert, parseInt, random, range, rangeRight, repeat, sampleSize, slice, some, sortBy, split, take, takeRight, template, trim, trimEnd, trimStart, and words. The purpose of this method is to "pass thru" values replacing intermediate results in a method chain sequence. This method returns the first argument it receives. Converts the first character of string to upper case. The order of result values is determined by the order they occur in the arrays. If func is an array or object, the created function returns true for elements that contain the equivalent source properties, otherwise it returns false. The corresponding value of each key is an array of elements responsible for generating the key. lodash empry array lodash get vs native for large json lodash find index in array of objects lodash is object array of arrays lodash _.reject if field in array lodash loop return same element of the other array in lodash lodash data Adds all own enumerable string keyed function properties of a source object to the destination object. Subsequent calls to the debounced function return the result of the last func invocation.Note: If leading and trailing options are true, func is invoked on the trailing edge of the timeout only if the debounced function is invoked more than once during the wait timeout.If wait is 0 and leading is false, func invocation is deferred until to the next tick, similar to setTimeout with a timeout of 0.See David Corbacho's article for details over the differences between _.debounce and _.throttle. // Underscore/Lodash - also called with _.contains, You don't (may not) need Lodash/Underscore, https://github.com/cht8687/You-Dont-Need-Lodash-Underscore, 大げさにする前にネイティブJavaScriptのオブジェクトおよび配列ユーティリティを活用するといいよ。, Lodashはもはや必要なくなったようだ。ネイティブで使えるJavaScriptメソッドの良いリストが出揃った今となっては。, これは認めざるを得ない。僕は#lodash乱用の罪を犯してきた。良いリソースだね。, you can read useful information later efficiently. As a result, we're left with little choice but to throw an error. (boolean): Returns true if object is a match, else false. after the two async saves have completed. Ramda vs Lodash. This method is like _.pullAll except that it accepts comparator which is invoked to compare elements of array to values. Creates a function that gets the argument at index n. If n is negative, the nth argument from the end is returned. GitHub Gist: instantly share code, notes, and snippets. (boolean): Returns true if value is array-like, else false. Lodash’s modular methods are great for: Iterating arrays, objects, & strings Manipulating & testing values Lodash is Checks if value is object-like. Escapes the RegExp special characters "^", "$", "", ". (boolean): Returns true if value is NaN, else false. The order of result values is determined by the order they occur in the arrays. Checks if path is a direct or inherited property of object. Iterates over elements of collection, returning the first element predicate returns truthy for. (Object): Returns the converted plain object. Converts the characters "&", "<", ">", '"', and "'" in string to their corresponding HTML entities.Note: No other characters are escaped. Both of these methods can be potent tools at your disposal and open up options that might take hundreds of lines of code to write yourself Use _.setWith to customize path creation.Note: This method mutates object. Converts value to an integer suitable for use as the length of an array-like object.Note: This method is based on ToLength. Reverts the _ variable to its previous value and returns a reference to the lodash function. Any additional arguments are provided to each invoked method. (Array): Returns the array of grouped elements. Creates a function that memoizes the result of func. (number): Returns the index of the matched value, else -1. Creates an array of own enumerable string keyed-value pairs for object which can be consumed by _.fromPairs. Change the following template settings to use alternative delimiters. Computes the mean of the values in array. Creates a function that invokes func, with the this binding and arguments of the created function, while it's called less than n times. Splits string by separator.Note: This method is based on String#split. Pads string on the left side if it's shorter than length. (string): Returns the upper cased string. Gets the element at index n of array. Dans le développement Javascript il y a deux librairies qui ont facilité la vie d’énormément de développeurs. An empty object is returned for uncloneable values such as error objects, functions, DOM nodes, and WeakMaps. ===. Checks if object conforms to source by invoking the predicate properties of source with the corresponding property values of object.Note: This method is equivalent to _.conforms when source is partially applied. Methods that retrieve a single value or may return a primitive value will automatically end the chain sequence and return the unwrapped value. If customizer returns undefined, assignment is handled by the method instead. (number): Returns the index of the found element, else -1. Creates a compiled template function that can interpolate data properties in "interpolate" delimiters, HTML-escape interpolated data properties in "escape" delimiters, and execute JavaScript in "evaluate" delimiters. (string): Returns the camel cased string. (All calculations were done on MacBook Pro in the latest Chrome browser, and on weaker devices with older browsers, the results can be much worse) Uses a binary search to determine the lowest index at which value should be inserted into array in order to maintain its sort order. Creates an object composed of keys generated from the results of running each element of collection thru iteratee. (RegExp): Used to detect data property values to be HTML-escaped. (Function): Returns the new debounced function. If end is not specified, it's set to start with start then set to 0. Source objects are applied from left to right. Subsequent calls to the throttled function return the result of the last func invocation.Note: If leading and trailing options are true, func is invoked on the trailing edge of the timeout only if the throttled function is invoked more than once during the wait timeout.If wait is 0 and leading is false, func invocation is deferred until to the next tick, similar to setTimeout with a timeout of 0.See David Corbacho's article for details over the differences between _.throttle and _.debounce. (Array): Returns the new property path array. The `opt-cli` pre-push functionality was removed from lodash just a few days after it was added (see 2cd12c3), but the documentation encouraging contributors to use it still remains.Remove to avoid confusion for new contributors.
