[Javascript] I have hit a brick wall

While the looping methods outlined may be easier to understand, this 
line of code is a gem!  My guess is that it also runs faster.  No need 
to know how many items in the array either.

So, if this looks strange, do a little study on stacks and lists.  These 
are long time standard constructs for those who studied programming in 
college courses, but are most likely missed by the many who are learning 
to code by the seat of their pants!
