(boolean): Returns true if the values are equivalent, else false. Computes the mean of the values in array. Any additional arguments are provided to each invoked method. The predicate is invoked with three arguments: (value, index|key, collection).Note: Unlike _.remove, this method returns a new array. Sets the value at path of object. Source objects are applied from left to right. Otherwise, the value must be unwrapped with _#value.Explicit chain sequences, which must be unwrapped with _#value, may be enabled using _.chain.The execution of chained methods is lazy, that is, it's deferred until _#value is implicitly or explicitly called.Lazy evaluation allows several methods to support shortcut fusion. Checks value to determine whether a default value should be returned in its place. A value is considered array-like if it's not a function and has a value.length that's an integer greater than or equal to 0 and less than or equal to Number.MAX_SAFE_INTEGER. Creates a new array concatenating array with any additional arrays and/or values. Functions and DOM nodes are compared by strict equality, i.e. Converts the first character of string to upper case. Checks if value is an Error, EvalError, RangeError, ReferenceError, SyntaxError, TypeError, or URIError object. This method is like _.isEqual except that it accepts customizer which is invoked to compare values. This method is like _.clone except that it recursively clones value. Computes the minimum value of array. (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) This method is like _.bind except it does not alter the this binding.The _.partial.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. --- jdalton, Lodash限定 (string): Returns the capitalized string. This method is like _.sum except that it accepts iteratee which is invoked for each element in array to generate the value to be summed. // => Find the source of "greeting.jst" under the Sources tab or Resources panel of the web inspector. This method is like _.reduce except that it iterates over elements of collection from right to left. + de 22 millions de téléchargement du module npm par semaine Sorties respectivement en 2009 pour Underscore et 2012 pour Lodash, elles font partie des librairies les plus populaires que tout d… This method is like _.zipObject except that it supports property paths. log (Number. (Array): Returns the new array of grouped elements. If customizer returns undefined path creation is handled by the method instead. '<% jq.each(users, function(user) { %>
  • <%- user %>
  • <% }); %>'. Checks if value is classified as a RegExp object. Truncates string if it's longer than the given maximum string length. 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. The customizer is invoked with up to six arguments: (objValue, othValue [, index|key, object, other, stack]). Actuellement,Lodashc’est : 1. The values false, null, 0, "", undefined, and NaN are falsey. Creates a slice of array with n elements dropped from the beginning. Iteration is stopped once predicate returns truthy. Creates a function that accepts arguments of func and either invokes func returning its result, if at least arity number of arguments have been provided, or returns a function that accepts the remaining func arguments, and so on. This method is like _.intersection except that it accepts comparator which is invoked to compare elements of arrays. 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。 The updater is invoked with one argument: (value).Note: This method mutates object. Iterates over elements of collection, returning an array of all elements predicate returns truthy for. // Use the HTML "escape" delimiter to escape data property values. Subsequent sources overwrite property assignments of previous sources.Note: This method mutates object. (Function): Returns the new invoker function. Converts string to an integer of the specified radix. (boolean): Returns true if value is a weak set, else false. The order of result values is determined by the order they occur in the arrays. This method is like _.merge except that it accepts customizer which is invoked to produce the merged values of the destination and source properties. The predicate is invoked with one argument: (value). The iteratees are invoked with one argument: (value). 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. log (_. isNaN (NaN)); // output: true // Native console. This method is like _.xor except that it accepts iteratee which is invoked for each element of each arrays to generate the criterion by which by which they're compared. Iterates over elements of collection, returning the first element predicate returns truthy for. Gets the value at path of object. Checks if value is less than or equal to other. If null safety is critical for your application, we suggest that you take extra Array See the ES spec for more details. log (isNaN (NaN)); // output: true // ES6 console. (boolean): Returns true if value is a finite number, else false. (boolean): Returns true if value is an integer, else false. // => Logs 'deferred' after one millisecond. Creates an array of own and inherited enumerable string keyed-value pairs for object which can be consumed by _.fromPairs. Lodash makes JavaScript easier by taking the hassle out of working with arrays, numbers, objects, strings, etc. The opposite of _.filter; this method returns the elements of collection that predicate does not return truthy for. If fromIndex is negative, it's used as the offset from the end of collection. Padding characters are truncated if they can't be evenly divided by length. (boolean): Returns true if value is an array-like object, else false. --- jdalton, これは代替の実装であることに注意してください。 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. Gets the next value on a wrapped object following the iterator protocol. '; // Use the `source` property to inline compiled templates for meaningful. Creates an object composed of keys generated from the results of running each element of collection thru iteratee. Creates a function that invokes func, with up to n arguments, ignoring any additional arguments. (boolean): Returns true if path exists, else false. Invokes func after wait milliseconds. Creates an object composed of keys generated from the results of running each element of collection thru iteratee. If customizer returns undefined path creation is handled by the method instead. Binds methods of an object to the object itself, overwriting the existing method.Note: This method doesn't set the "length" property of bound functions. The iteratee is invoked with one argument: (value). // Use the `sourceURL` option to specify a custom sourceURL for the template. A step of -1 is used if a negative start is specified without an end or step. // Use the ES template literal delimiter as an "interpolate" delimiter. (boolean): Returns true if any element passes the predicate check, else false. The performance difference you see here is almost always … Creates a function that negates the result of the predicate func. (boolean): Returns true if value is greater than other, else false. The predicate-function pairs are invoked with the this binding and arguments of the created function. An empty object is returned for uncloneable values such as error objects, functions, DOM nodes, and WeakMaps. The predicate is invoked with two arguments: (value, key). Iterates over own enumerable string keyed properties of an object and invokes iteratee for each property. The opposite of _.pickBy; this method creates an object composed of the own and inherited enumerable string keyed properties of object that predicate doesn't return truthy for. Iteratee functions may exit iteration early by explicitly returning false. 最初のカウント数分呼び出された後に実行される関数のバージョンを作成します。次に進む前に、全ての非同期呼び出しが完了したことを確認するための非同期応答のグルーピングに役立ちます。. The customizer is invoked with three arguments: (nsValue, key, nsObject).Note: This method mutates object. Splits string by separator.Note: This method is based on String#split. (boolean): Returns true if value is nullish, else false. 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。 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. (Object): Returns the composed aggregate object. This method is like _.set except that it accepts customizer which is invoked to produce the objects of path. I myself enjoys its functional way to process collections, es But Lodash’s _.map is more powerful, in that it works on objects, has iteratee / predicate shorthands, lazy evaluation, guards against null parameter, and has better performance. (boolean): Returns true if value is a function, else false. Performs a SameValueZero comparison between two values to determine if they are equivalent. The iteratee is invoked with three arguments: (value, key, object). (string): Returns the start cased string. Converts all elements in array into a string separated by separator. To escape additional characters use a third-party library like he.Though the ">" character is escaped for symmetry, characters like ">" and "/" don't need escaping in HTML and have no special meaning unless they're part of a tag or unquoted attribute value. Creates an object composed of the object properties predicate returns truthy for. (Array): Returns the new array of regrouped elements. If customizer returns undefined, comparisons are handled by the method instead. Checks if value is classified as a Symbol primitive or object. This method is like _.update except that it accepts customizer which is invoked to produce the objects of path. (boolean): Returns true if value is a DOM element, else false. "Cross-browser" is the primary reason why developers choose jQuery. Help us understand the problem. A value is object-like if it's not null and has a typeof result of "object". (Function): Returns the new composite function. The comparator is invoked with two arguments: (arrVal, othVal).Note: Unlike _.pullAllWith, this method returns a new array. The func predicate is invoked with the this binding and arguments of the created function. (boolean): Returns true if value is less than or equal to other, else false. Converts value to an integer suitable for use as the length of an array-like object.Note: This method is based on ToLength. If a portion of path doesn't exist, it's created. This is a post on the lodash method _.join, as well as the corresponding Array.prototype.join method that is being referenced. Checks if value is classified as an ArrayBuffer object. (boolean): Returns true if value is a set, else false. Assigns own enumerable string keyed properties of source objects to the destination object. Creates an object composed of keys generated from the results of running each element of collection thru iteratee. (boolean): Returns true if value is a plain object, else false. (RegExp): Used to detect code to be evaluated. Checks if value is object-like. Creates a slice of array from start up to, but not including, end.Note: This method is used instead of Array#slice to ensure dense arrays are returned. Checks if predicate returns truthy for any element of collection. Webクリエイターであり、Node.js/io.jsのファシリテーターでもあるtherebelrobot氏, 配列のすべての要素が与えられた関数によって実行されるテストに合格するかどうかテストします。, 配列のいくつかの要素が与えられた関数によって実行されるテストに合格するかどうかテストします。, 累積した値と配列のそれぞれの値(左から右へ)を単一の値に減らすために関数を適用します。, このメソッドは、右から左にコレクションの要素を反復処理することを除けば _.reduce のようなものです。, 提供された関数によって実行されるテストをパスした全ての要素を含む新たな配列を生成します。, 配列内の要素が提供されたテスト関数をパスした場合、配列の値を返します。それ以外の場合は、 undefined が返されます。, 与えられた要素に該当する配列内の最初のインデックス、もしくはそれが存在しない場合は、 -1 を返します。, 与えられた要素に該当する配列内の最後のインデックス、もしくはそれが存在しない場合は、 -1 を返します。, 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りません。これは通常 NaN に変換される値を安全に渡せることを意味しますが、実際の NaN と同じ値ではありません。これは数値型の値が NaN でもあるということを意味し、 true を返します。 Number.isNaN(), Lodashの _.isNaN は、グローバルの isNan とは異なるES6の Number.isNaN に等しいです。 And reduceRighttoo to lower case just like string # replace when the click event is fired but!
