SOLUTION: JavaScript recursive binary search, REFACTORED!

I noticed that there was a JavaScript solution for the refactored recursive binary search. Here is my solution:

const listOfNums = [1, 2, 3, 4, 5, 6, 7, 8]; 
const targetNum = 2; 

function recursive(list, target, start=0, end=null) {
    if (!end) {
        end = list.length - 1;

    if (start > end) {
        return null;

    const midpoint = Math.floor((start + end) / 2);

    if (list[midpoint] == target) {
        return midpoint;
    } else if (list[midpoint] < target) {
        return recursive(list, target, midpoint + 1, end);
    } else {
        return recursive(list, target, start, midpoint - 1);

function verify(result) {
    console.log(`target found: ${result}`);

result = recursive(listOfNum, targetNum);
