Write some code, that will flatten an array of arbitrarily nested arrays of integers into a flat array of integers. e.g. [[1,2,[3]],4] -> [1,2,3,4].
/*
Example of a flatten array method using recursion. If the original array is
large do NOT use this funtion. Too much memory is used off the stack.
*/
let array = [[1,2,[3]],4];
let newArray = flattenRecursive(array);
function flattenRecursive(array, results = []) {
for (let i = 0; i < array.length; i++) {
if (Array.isArray(array[i])) {
flattenRecursive(array[i], results); // called until the inner most array is reached
} else {
results.push(array[i]);
}
}
return results;
}
