Benchmark: Arguments leaking

Script Preparation code:

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