"I highly recommend downloading the Script documentation from Microsoft"

I had a look at it, and now I'm confused. Am I the only one wondering what windows OS scripting has to do with javascript?

I’m trying to decide if Prototype offers any value to me. Can anyone tell me why all these observe and bind syntaxes are any better than the “var self = this”??

If you want some help understanding closures in JS I found this great page on closures in JS

Thanks Peter for one of the best and most useful javascript related reference ever!

ahem. let me try that again:

This means of "enforcing" scope is used in dragdrop.js, though the one you describe is more compact. They have things like this:

this.eventMouseDown=this.startDrag.bindAsEventListener(this);

followed by:

Event.observe(this.handle, "mousedown", this.eventMouseDown);

this is one case where putting it all smashed together (as you did) improves readability...
