For the first Liverpool Girl Geeks event I did a bit of an Intro to Programming workshop in Javascript, here are the slides and the notes:
The enumeration example didn't work because enumeration does not actually exist in Javascript ^^;;

That's what happens when you switch languages all the time xD
The code for the language intro follows pretty much what we did but is more concise.
In this one you'll need, before you run the code, to turn the console tab on and the output tab off, otherwise you won't see the code execution results, since everything happens in the console.
The Three.js page you can play with:
