Reeborg knows multiple programming languages

I wish I were in Montreal to visit my daughter, eat some delicious Saint-Sauveur bagels for breakfast, a good La Banquise poutine and some Montreal Smoked Meat for lunch... and, of course, attend Pycon.  Alas....

In the meantime, a quick update: Reeborg now knows Python, Javascript and CoffeeScript.  The old tutorials are gone as Reeborg's World has seen too many changes.  I now am in the process of writing the following tutorials, all using Reeborg's world as the test environment

1. A quick introduction to Python (for people that know programming in another language)
2. A quick introduction to Javascript (same as above)
3. A quick introduction to CoffeeScript (same as above)
4. An introduction to programming using Python, for absolute beginners
5. An introduction to programming using Javascript, for absolute beginners
6. An introduction to Object-Oriented Programming concepts using Python
7. An introduction to Object-Oriented Programming concepts using Javascript

Note that I have two "versions" of Javascript, one that uses JSHint to enforce good programming practices (and runs the code with "use strict"; option) and one that is the normal permissive Javascript.

If anyone knows of any other transpilers written in Javascript that can convert code client-side from language X into Javascript (like Brython does for Python, or CoffeeScript does naturally), I would be interested in adding them as additional options.
