Re-Learning JavaScript

One of my main personal goals for this semester is to learn / master JavaScript.

I've skimmed several JavaScript texts over the years and read many more articles. Simon's (Re)-Introduction to JavaScript is hands down the best cut to the chase run down on JavaScript I've read.

I've also had my JavaScript vars returning NaN time and time again. I knew its because I had messed up the type of the var but didn't know that there was actually a special value for Not-A-Number and what the common cause for it was. But now I do:
'This turns up when you do things like trying to convert a non-numeric string in to a number.'

During last weeks lecture there was a slide with various logos of standards associations. One logo was for ECMA, known for its ECMAScript (JavaScript) standard. Up until that point thats all I knew about ECMA. Prompted by a question from a client that I can now answer: "What does ECMA stand for?"

European Computer Manufacturers Association

Yay, one more acronym learnt :P
