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 ;...
A practical guide to flattening JavaScript arraysES2019 introduced two new methods to the Array prototype: flat and flatMap. They are both very useful to what we want to do: flatten an array.Let’s see how they work.But first, a word of warning: only Firefox 62+, Chrome 69+, Edge ...
