Thanks, the window[] tip was helpful.

I found out about the window[] method after I wrote this (it's been long). Yes, that method is definitely faster, and for all practical purposes, serves our need.

The eval() function works for this, but is very inefficient. You'd be much better off evaluating such variables through the use of brackets. For example, since all global variables are put into the window class by default, then if you have something like: var y = 'some string' var x = y

You could get to the value of y through x by window[x], which would be much more efficient in terms of resources than using eval().
