Shift Array Values
Given an array, shift all values forward, dropping the first value and leaving an extra '0' value at the end.
function shift_array(arr) { //your code return arr; } shift_array([1,2,3,4]);
function shift_array(arr) { for (var i = 1; i < arr.length; i++) { arr[i-1] = arr[i]; } arr[arr.length-1] = 0; return arr; } shift_array([1,2,3,4]);
