It is rather moot now that we the flat() method. This one uses the spread with .concat()
function flattenArray(array) {
let currentIndex = 0;
let faltArray = [];
while (currentIndex !== array.length) {
const instanceOfArray = array[currentIndex] instanceof Array;
if (!instanceOfArray) {

tried not to use the Mozilla reduce function like others did since it’s basically just laid out for them.
function flattenArray(array) {
// Write your code here
let a = []
for(let x = 0; x < array.length; x++){
if(typeof array[x] === "object"){
a = a.concat(array[x])
}else{
a.push(array[x])
}

return a;
