Input array: [1, 2, [3, 4, [5, 6, [7, 8, [9]]]], 10]
Output array: [1,2,3,4,5,6,7,8, 9, 10]

Is there a way to get the output array without using multiple loops?

console.log([1, 2, [3, 4, [5, 6, [7, 8, [9]]]], 10].flat(Infinity));

Use 'flat' method to flatten the array. Or you can also use underscore module method.

You can add an infinity argument to flat to get all the numbers from the many nested arrays.

const data = [1, 2, [3, 4, [5, 6, [7, 8, [9]]]], 10];
const out = data.flat(Infinity);
console.log(out);
