Answer 1

Are you trying to do something more complicated then just add an alias for "push" called "Add"?

If not, it would probably be best to avoid doing this. The reason I suggest this is a bad idea is that because Array is a builtin javascript type, modifying it will cause all scripts Array type to have your new "Add" method. The potential for name clashes with another third party are high and could cause the third party script to lose its method in favour of your one.

My general rule is to make a helper function to work on the Array's if it doesnt exist somewhere already and only extend Array if its extremely necessary.
