(boolean): Returns true if value is greater than other, else false. Creates a debounced function that delays invoking func until after wait milliseconds have elapsed since the last time the debounced function was invoked. If you have been or are working with javascript then you should have heard of lodash. Var extend = require( 'lodash/fp/extend '); Mapping Immutable auto-curried iteratee-first data-last methods sound great, but what does that really mean for each method? The comparator is invoked with two arguments: (arrVal, othVal).Note: Unlike _.differenceWith, this method mutates array. The order and references of result values are determined by the first array. Converts value to a safe integer. '; // Use the `source` property to inline compiled templates for meaningful. Creates a new array concatenating array with any additional arrays and/or values. (Array): Returns the new array of filtered values. (boolean): Returns true if value is a safe integer, else false. However, this would not create a key-value pair map. 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 order of result values is determined by the order they occur in the arrays. If orders is unspecified, all values are sorted in ascending order. (Array): Returns the new concatenated array. Syntax: _.map(list, function) To enable this configuration, use the extends property in your package.json. Checks if value is classified as a Number primitive or object.Note: To exclude Infinity, -Infinity, and NaN, which are classified as numbers, use the _.isFinite method. Data properties may be accessed as free variables in the template. This method is like _.intersection except that it accepts comparator which is invoked to compare elements of arrays. 2 - Simple _.map example in lodash. Deburrs string by converting Latin-1 Supplement and Latin Extended-A letters to basic Latin letters and removing combining diacritical marks. Checks if value is classified as a WeakMap object. If a property name is provided for callback the created ".pluck" style callback will return the property value of the given element. Any additional arguments are provided to the invoked method. (Array): Returns the new array of removed elements. Gets n random elements at unique keys from collection up to the size of collection. Multiple examples cover many Lodash functions. (string): Used to reference the data object in the template text. The use of _ in languages as a placeholder. This library uses double underscore instead to differentiate it from the native library, which already uses a single underscore in some circumstances. The iteratee is invoked with three arguments: (value, key, object). The iteratee is invoked with one argument: (value). futil-js is a set of functional utilities designed to complement lodash. Defers invoking the func until the current call stack has cleared. Checks if value is a plain object, that is, an object created by the Object constructor or one with a [[Prototype]] of null. Pads string on the left side if it's shorter than length. Installation. Gets the size of collection by returning its length for array-like values or the number of own enumerable string keyed properties for objects. Creates a function that returns the result of invoking the given functions with the this binding of the created function, where each successive invocation is supplied the return value of the previous. Version 3.4.0 has recently been released. This method is like _.assign except that it recursively merges own and inherited enumerable string keyed properties of source objects into the destination object. The debounced function comes with a cancel method to cancel delayed func invocations and a flush method to immediately invoke them. (Function): Returns a new lodash function. The 2nd example for invokeMap fp don't seem to work, but they work with regular lodash. // => [{ 'user': 'barney', 'age': 36, 'active': true }]. // => Logs 'done saving!' Lodash-Fun Some fun utilities, logic functions and stuff that is not included with lodash/fp. Pastebin is a website where you can store text online for a set period of time. Recommended configuration. Creates an array of grouped elements, the first of which contains the first elements of the given arrays, the second of which contains the second elements of the given arrays, and so on. (string): Returns the camel cased string. Use _.remove to remove elements from an array by predicate. See _.isEqual for a list of supported value comparisons. The corresponding value of each key is an array of elements responsible for generating the key. (boolean): Returns true if string starts with target, else false. (boolean): Returns true if number is in the range, else false. Invokes the iteratee n times, returning an array of the results of each invocation. Use _.map for forward-compatibility. (Object): Returns the new inverted object. Close • Posted by 4 minutes ago. lodash fp docs. Creates an array of values by running each element in collection thru iteratee. A safe integer can be compared and represented correctly. arrays, functions, objects, regexes, new Number(0), and new String('')). (Object): Returns the next iterator value.
