I was partially inspired by your blog post right here and also by Peter Michaux’s blog post on macros (http://peter.michaux.ca/articles/macros-in-javascript-please) and I did a little hacking. (Emphasis on hack).

Let me know what you think.

The JavaScript has lexical scoping http://en.wikipedia.org/wiki/Scope_(programming)#Static_scoping_.28also_known_as_lexical_scoping.29 which, combined with anonymous functions, becomes my favorite thing about JavaScript. Well, that and object literals.

The ECMA standard is probably really dense (I don’t know I haven’t read it) and I think a better way to start really understanding JavaScript is to read all of Douglas Crockford’s essays (http://javascript.crockford.com/) and his book JavaScript: The Good Parts.

@Matthieu:

Great post! I wish that I could use ~> client side! I love that idea.

Just for clarification, would you replace all instances of undefined with null? I rather like being able to do this:

function (foo) {
foo = foo || “bar”
return foo;
}

I haven’t poked around with Rhino, but I have been having so much fun with JS that I’m thinking about replacing my django install some time in the future. Maybe. Or maybe for some other project. There’s so much that I want to try, but so little time. Arc and ocaml are on the list too.

I remember carefully reading ECMAScript spec and trying to memorise it
Guess what? Despite my most honest efforts I’ve failed
I never became a Javascript guru alas

I remember also having a difficulty in groking variable scopes
