CodeWars: Remove Zeroes Solution

1function removeZeros(array) {
2  // Sort "array" so that all elements with the value of zero are moved to the
3  // end of the array, while the other elements maintain order.
4  // [0, 1, 2, 0, 3] --> [1, 2, 3, 0, 0]
5  // Zero elements also maintain order in which they occurred.
6  // [0, "0", 1, 2, 3] --> [1, 2, 3, 0, "0"]
7
8  // Do not use any temporary arrays or objects. Additionally, you're not able
9  // to use any Array or Object prototype methods such as .shift(), .push(), etc
10
11  // the correctly sorted array should be returned.
12  let N = array.length
13  for (let i = 0; i < N; i++) {
14    let times = N - i
15    while ((array[i] === 0 || array[i] === "0") && times--) {
16      for (let j = i + 1; j < N; j++) {
