Array#clear Useful JavaScript Game Extension #28

Here’s a useful little method that empties out an array. Sure you could type myArray.length = 0; but that is kind of weird. For some reason myArray.clear() just makes more sense to me.

/**
* Empties the array of it's contents. It is modified in place.
*
* @type Array
* @returns this, now emptied.
*/
Array.prototype.clear = function() {
  this.length = 0;
  return this;
};
