arr-filter-function

Fast filter array to have only function values. But also allow you to give iterator function which will be called on each element of the array that is function - much like array.map functionallity. Useful when you want to filter, but also want to map in same time.

Install

npm i arr-filter-function --save
npm test

arrFilterFunction

Filter array for function values and iterate over them if needed.

• <arr> {Array}
• [iterator] {Function}
• returns {Array}: filtered array, containing only functions

Example

var arrFilterFunction = require('arr-filter-function')

function fn1 () {}
function fn2 () {}
function fn3 () {}

var arr = arrFilterFunction([fn2, 'abc', [1, 2, [fn3, 3]], fn1])
//=> [fn2, fn1]

Or you can give iterator function which will be called on each element of array.

var arrFilterFunction = require('arr-filter-function')

function fn1 () {}
function fn2 () {}
function fn3 () {}

var arr = [{foo: 'bar'}, [fn1, 1, 2], fn3, fn2]
var res = arrFilterFunction(arr, function (fn) {
  return fn
})
//=> [fn3, fn2]
