Tell us what’s happening:
Can somebody please explain to me my confusion in this problem, though i already solved the problem but i was bewildered when line number 9 does not exist, it return undefined? As a challenge to myself i turn this into recursive function but when i only use the return in line number 3 it does not return the actual result though res = the desired result;

  **Your code so far**

function chunkArrayInGroups(arr, size, res = []) {
// return when arr argument is empty
if(arr.length < 1) return res;
// slice through array
res.push(arr.slice(0, size));
// do a recursive
chunkArrayInGroups(arr.slice(size),size,res);
// if not present return undefined
return res;
}

chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6, 7, 8], 4);

You aren’t doing anything with the return value of this function call
