I was having some troubles figuring out how do use this. So I will go over the best way that I figured CallJS pecularities. I wanted the real time clock for my game so it was a bit of effort :D
var data = [process your data here];
1. Create a var to hold your processed data.
2. process your data in JS as you normally would
3. present the data variable by itself on it's own line.
anyways. if i'm wrong post what your trying to process and I'll see if i can help sort it out :D
