Using a namespace and a GLOBALS property is definitely a good way to do the same. Hi Marco,

I used the dollar sign just for the sake of the PHP analogy, and a little bit as a joke in the spirit of "let's make JS like our other favorite language" (looking at you, prototype.js).

Using a namespace and a GLOBALS property is definitely a good way to do the same.

Just out of curiosity though: why use a dollar sign? Just because it's more PHP-ish or is there another reason? Also: In a YUI context you may want to use YAHOO.GLOBALS maybe? :) Interesting idea Stoyan!

The scope actually comes from the parent. Undefined variables appear to be global, that's true. Scoping is really "weird" in JS if you've never worked in another language that does closures. See: http://en.wikipedia.org/wiki/Closure_(computer_science) Not saying you're wrong, of course, but thinking about JavaScript scopes the same way you think about PHP scopes is likely to lead to maintenance/development trouble down the road (-: S They aren't really globals in JavaScript.

What I really do like though, is that the stuff you want to be global, isn't mixed in with all the clutter that the browser (especially IE) wants to be global. e.g. if you run your globs code on a blank window in IE, you'll get a bunch of objects and properties before adding a single variable.
