Howdy, Grant.
First, that's awesome you're going to use it in the classroom. Thanks!
That's interesting. When I create a new .
js file it's empty. It sounds like something has mucked up the templates and/or default documents.
I wanted to use WebMatrix when recording the book, but it was in beta (and I didn't want to use beta software). It has a built-in web server, which is great for Ajax stuff. Another excellent editor is Sublime Text 2, but it's not free. Notepad++ or Notepad2 are good editors.
Autocomplete can be a double-edged sword. It's nice to have, but it is also easy to get dependent on it. In JavaScript's case, I'd say it's more a hindrance than tool. Autocomplete is hard to get right in a language like JavaScript, and while support is better than it used to be, it still leaves a lot to be desired.
