Not a JS coder here.. Rails mostly..

But yeah. Javascript 100%. It's the easiest language to get things working, and it works on crappy systems, and it's fun.

I'd pick rails over python for two reasons. 1. tabbing for logic sucks to refactor. 2. Immutable data is a complexity that's not common, and might be something to cover later.

I'd add the use of GITHUB to the mix too. Projects and Issues are something key to every developers life.

My kids 12 (grade 7) and building an HTML/CSS/JS page on github is exciting and engaging. Static Blog, but fun.
