// The arguments variable in a function is not a real Array. So to be able to
// slice and dice it you need to convert OR handle it as an array:
// 1) Creating a new Array:
[].slice.call(arguments).doWhatEver // slower
// 2) Getting the Array Prototype:
Array.prototype.slice.call(arguments).doWhatEver // faster

// To test something is an Array or not:
var isArray = ({}).toString.call([]);
// But why not? ([]).toString
