I use prototyping a lot for standard Javascript classes like Array. The function is then available to any Array that you create. For example:

      Array.prototype.contains = function (a)
      {
        for (var r = 0; r < this.length; r++)
          {
            if (this[r] == a) { return true; }
          }
        return false;
      }





You can then just use 'myArray.contains(myValue)' to find if the value is in the Array. If you were doing this with a function, you would need to send both the Array and the value to the function, so it's a little less elegant.
