Benchmark: Array Initialization Types

Script Preparation code:

var times = 1000;

Tests:

Literal
var arr = []; for (var i = 0; i < times; i++) { arr[i] = 1337; }
Array()
var arr = new Array(); for (var i = 0; i < times; i++) { arr[i] = 1337; }
Array(length)
var arr = new Array(times); for (var i = 0; i < times; i++) { arr[i] = 1337; }
Literal overflow
var arr = []; for (var i = 0; i <= times; i++) { arr[i] = 1337; }
Array() overflow
var arr = new Array(); for (var i = 0; i <= times; i++) { arr[i] = 1337; }
Array(length) overflow
var arr = new Array(times); for (var i = 0; i <= times; i++) { arr[i] = 1337; }
