Benchmark: Array constructor vs literal performance - 1000 items

Tests:

Array constructor - 1000 items
var n = 1000; var arr = new Array(n); for (var i = 0; i < n; i++) { arr[i] = i; }
Array literal - 1000 items
var n = 1000; var arr = []; for (var i = 0; i < n; i++) { arr.push(i); }
Array literal (assign by index) - 1000 items
var n = 1000; var arr = []; for (var i = 0; i < n; i++) { arr[i] = i; }
Array literal (explicit length) - 1000 items
var n = 1000; var arr = []; arr.length = n; for (var i = 0; i < n; i++) { arr[i] = i; }
