I feel like you’re missing one of the finer points in this bracket/brace post; braces define Objects – not Arrays!

The following are essentially the same:

var myArray = [];
var myArray = new Array();

… as are:

var myObject = {};
var myObject = new Object();

Javascript is by no means perfect – so you’ll have to know the pitfalls, like erroneously mixing keys and indexes in an Array (like you can do in PHP – bad).
As javascript doesn’t have associative arrays Objects are the closest thing.

@Tim: That’s what I get from it. Please let me know if I’m wrong.

This is interesting. So if you use []‘s in a key=>value array it just won’t work or it’s simply improper usage?

I must admit, I’ve wondered this myself with the MOO as they seem to have pretty creative looking code conventions (that really make a lot of sense).
