Of course I have done the same, and also included for loops with
for-in (most expensive and slow) and while loops doing the same
conditional checking.

But here comes the catch: While this is true with real JS arrays try
it with a DOM nodelist and you will see that there is no speed
difference between "my" method and the backward looping or two
variable versions.

I didn't claim this to be a perfect solution, but I like the idea of
not having to read the length and being able to loop with a real
iterator and steps other than one.
