I also use "i" in my for loops. Always!
But I still find it difficult to understand when there are more than one 
index in use.

The thing here is that I couldn't understand the function top to bottom..
"j" was used both by the incrementer in the for loop, in the indexOf and 
the if statement. I had to get to the indexOf before I could understand 
what "j" was.

Of course, I'm just pointing out very small areas of potential 
improvement as I've only covered 5% of the spec and 1% of the stdlib :)
