ok, so when i do array=array2 then change something in array2 it changes array. how do i prevent this?

Thought I should explain why, but it ain't an answer, so here it goes: objects and arrays are passed by reference, unlike numbers and strings. — Christian

Do..

b = a.slice()

Why? Because assignment would just reference the origin object. slice or concat would create a new object.
