Anyway, he was thrilled by jsdares because of the gaming approach. He was excited to do the first 3 robots tutorials, and then he got tired but asked me to send him the link to the site. Those were the first programming lines he wrote.

There's already a few good introductions to programming in JavaScript in English, but very few ones in Portuguese using this new approach.
