Introduction to JavaScript Flatten Array. Flatten means the array which is nested to some level of depth. In Javascript, arrays can be nested with any depth, these  Nov 21, 2020 We are required to write a JavaScript function that takes a nested array, ideally nested to any arbitrary level. Our function should then prepare  this is my attempt into doing it in a very verbose way with old JavaScript. function flattenArrayRaw(arr) {. // Get array length. var arrayLength = arr.length.

By default, depth will be 1. Returns new array according to depth specified with sub-array elements concatenated. function flatten (ary) { return ary.reduce (function (a, b) { if (Array.isArray (b)) { return a.concat (flatten (b)) } return a.concat (b) }, []) } Let's adopt some ES6 syntax which makes it even shorter, in one line. const flatten = (ary) => ary.reduce ((a, b) => a.concat (Array.isArray (b) ? flatten (b) : b), []) This solution runs a while loop that pushes each element into a new array. When the next element of an array is a nested array, the function recursively calls itself and does the same for its function flatten (arr) { return [].concat (arr) } Is simply expands arr and passes it as arguments to concat (), which merges all the arrays into one.
