Tests:
  • Array constructor - 10 items

    x
     
    var n = 10;
    var arr = new Array(n);
    for (var i = 0; i < n; i++) {
      arr[i] = i;
    }
  • Array literal - 10 items

     
    var n = 10;
    var arr = [];
    for (var i = 0; i < n; i++) {
      arr.push(i);
    } 
  • Array literal (assign by index) - 10 items

     
    var n = 10;
    var arr = [];
    for (var i = 0; i < n; i++) {
      arr[i] = i;
    } 
  • Array literal (explicit length) - 10 items

     
    var n = 10;
    var arr = [];
    arr.length = n;
    for (var i = 0; i < n; i++) {
      arr[i] = i;
