Benchmark: Arguments leaking - IE version

Script Preparation code:

var leakyArguments = function () {
  return other(arguments)
}
var nonLeakyArguments = function  (args) {
  return other(args)
}
var copyArgs = function  () {
  var array = new Array(arguments.length)

  for (var i = 0; i < array.length; i++) {
    array[i] = arguments[i]
  }

  return other(array)
}

var sliceArguments = function () {
  var array = Array.prototype.slice.apply(arguments)
  return other(array)
}

var other = function (toSum) {
  var total = 0
  for (var i = 0; i < toSum.length; i++) {
    total += toSum[i]
  }
  return total
}

Tests:

Array.prototype.slice arguments
sliceArguments(1, 2, 3)
copyArgs
