You are NOT allowed to use any temporary arrays or objects. You are also not allowed to use any Array.prototype or Object.prototype methods.

console.log(removeZeros([7, 2, 3, 0, 4, 6, 0, 0, 13, 0, 78, 0, 0, 19, 14]));//[7, 2, 3, 4, 6, 13, 78, 19, 14, 0, 0, 0, 0, 0, 0]

• my answer

function removeZeros(arr) {    var len = arr.length;    var temp;    for (var i = 0; i < len; i++) {        if (arr[i] === 0 || arr[i] === '0') {            temp = arr[i];            for (var j = i--; j < arr.length-1; j++) {                arr[j] = arr[j+1];            }            arr[arr.length-1] = temp;            len--;        }    }    return arr;}
