If fromIndex is negative, it's used as the offset from the end of collection. (*): Returns the matched element, else undefined. The opposite of _.filter; this method returns the elements of collection that predicate does not return truthy for. (e.g. Removes trailing whitespace or specified characters from string. 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. this.setState( set(['object', index, prop], e.target.value) ) The iteratee is invoked with three arguments:(value, key, object). (Function): Returns the new memoized function. Executes the chain sequence to resolve the unwrapped value. The lodash library does not have typecript definitions included in modular format so the import statements do not work. This method is like _.uniq except that it accepts iteratee which is invoked for each element in array to generate the criterion by which uniqueness is computed.

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. Lodash began as a fork of the popular Underscore.js library but since then has managed to become its superset, adding new features and performing much better. (boolean): Returns true if string starts with target, else false. This method is like _.unzip except that it accepts iteratee to specify how regrouped values should be combined. (Function): Returns the new throttled function. The iteratee is invoked with one argument:(value). Index all objects by the chosen key. The predicate-function pairs are invoked with the this binding and arguments of the created 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. Elements are taken until predicate returns falsey. import map from "lodash/fp/map"; map((x) => x*2)([1, 2, 3]); // We have this! Checks if value is classified as a Map object. (Object): By default, the template delimiters used by lodash are like those in embedded Ruby (ERB) as well as ES2015 template strings. This method is like _.zipObject except that it supports property paths. Rambda is nice enough, but I feel like Lodash' interface is far more user friendly - for example, lodash collection methods always pass through the item, index and collection to work with. Creates a debounced function that delays invoking func until after wait milliseconds have elapsed since the last time the debounced function was invoked. The iteratee is invoked with one argument: (value).Note: Unlike _.differenceBy, this method mutates array. Use Git or checkout with SVN using the web URL. The iteratee is invoked with one argument: (value). To enable this configuration, use the extends property in your package.json. The customizer is invoked with five arguments: (objValue, srcValue, key, object, source).Note: This method mutates object. arrays, functions, objects, regexes, new Number(0), and new String('')). Creates a throttled function that only invokes func at most once per every wait milliseconds. (Function): Returns the new curried function. This library uses double underscore instead to differentiate it from the native library, which already uses a single underscore in some circumstances. Lodash's map method works exactly like Javascript native array method except that it has a sweet upgrade. This method is like _.mean except that it accepts iteratee which is invoked for each element in array to generate the value to be averaged. The order and references of result values are determined by the first array. Computes the minimum value of array. If prefix is given, the ID is appended to it. set is lodash.fp function. (boolean): Returns true if value is greater than other, else false. It displays the result as a list on the console. Auto Currying in Haskell, Lodash-Fp, Ramda, Elm. Subsequent calls to the created function return the result of the last func invocation. Example: Docs - weekly downloads - size If customizer returns undefined, cloning is handled by the method instead. This method is like _.assign except that it recursively merges own and inherited enumerable string keyed properties of source objects into the destination object. Creates a function that invokes func with arguments arranged according to the specified indexes where the argument value at the first index is provided as the first argument, the argument value at the second index is provided as the second argument, and so on. Gets n random elements at unique keys from collection up to the size of collection. Creates a slice of array with n elements taken from the beginning. The _.map() function is an inbuilt function in Underscore.js library of the JavaScript which is used to produce a new array of values by mapping each value in list through transformation function (iteratee). Take note: There is a much more specific method for this use-case: _.pluck. (string): Returns the kebab cased string. The customizer is invoked with three arguments: (nsValue, key, nsObject).Note: This method mutates object. Lodash tutorial covers the Lodash JavaScript library. (boolean): Returns true if value is a function, else false. As a result, we're left with little choice but to throw an error. The sign of -0 is preserved. The predicate is invoked with three arguments: (value, index|key, collection). If customizer returns undefined path creation is handled by the method instead. Sections of a chain sequence qualify for shortcut fusion if the section is applied to an array and iteratees accept only one argument. Creates an array of values corresponding to paths of object. Checks if value is likely an arguments object. (number): Returns the index of the matched value, else -1. Lodash/fp always creates a NEW object. (Array): Returns the new duplicate free array. Create a new pristine lodash function using the context object. (boolean): Returns true if value is an object, else false. (RegExp): Used to detect data property values to inject. This method is like _.assign except that it iterates over own and inherited source properties.Note: This method mutates object. The func is invoked with the last arguments provided to the debounced function. A safe integer can be compared and represented correctly. Checks if predicate returns truthy for all elements of collection. (Array): Returns the new array of regrouped elements. Lodash first and last array elements. (Function): Returns the new capped function. Subsequent sources overwrite property assignments of previous sources.Note: This method mutates object. Use _.map for forward-compatibility. (boolean): Returns true if value is nullish, else false. The comparator is invoked with two arguments: (arrVal, othVal).Note: Unlike _.differenceWith, this method mutates array. It takes two indexes: the starting and ending index, where the starting index is inclusive and the ending is exclusive. (string): Returns the lower cased string. Pseudo Code. This method is like _.find except that it iterates over elements of collection from right to left. times. times. The debounced function comes with a cancel method to cancel delayed func invocations and a flush method to immediately invoke them. SYNC missed versions from official npm registry.. lodash v4.17.20. Converts string, as space separated words, to lower case. This method is like _.find except that it returns the index of the first element that passes the callback check, instead of the element itself. “get unique values in array lodash” Code Answer . (Array): Returns the new array of combined values. Checks if string starts with the given target string. 3. The iteratee is invoked with one argument: (value). Produces a random number between the inclusive lower and upper bounds. If you have been or are working with javascript then you should have heard of lodash. Lodash-Fun Some fun utilities, logic functions and stuff that is not included with lodash/fp. If object is a map or set, its entries are returned. lodash Site | Docs | FP Guide | Contributing | Wiki | Code of Conduct | Twitter | Chat The Lodash library exported as a UMD module. This method is like _.reduce except that it iterates over elements of collection from right to left.

(boolean): Returns true if path exists, else false. Deburrs string by converting Latin-1 Supplement and Latin Extended-A letters to basic Latin letters and removing combining diacritical marks. Creates a function that iterates over pairs and invokes the corresponding function of the first predicate to return truthy. Checks if value is a plain object, that is, an object created by the Object constructor or one with a [[Prototype]] of null. ", "(", ")", "[", "]", "{", "}", and "|" in string.
