This post will discuss how to flatten an array in JavaScript... The Array.flat() function is a built-in function that returns a new array with all sub-array elements concatenated into it recursively up to a specified depth.
How do you flatten array in javascript If you are given an array that contains literals, arrays and objects and you want to get all the values to one array. Here is the snippet using recursive function to attain that. functionimplode(arr){varres = [];for(vari =0; i < arr.length ;...
