How can I simulate macros in JavaScript?

Question

I know that JavaScript doesn't support macros (Lisp-style ones) but I was wondering if anyone had a solution to maybe simulate macros? I Googled it, and one of the solutions suggested using eval(), but as he said, would be quite costly.

They don't really have to be very fancy. I just want to do simple stuff with them. And it shouldn't make debugging significantly harder :)

Answer 1

You could use parenscript. That'll give you macros for Javascript.

Answer 2

A library by Mozilla (called SweetJS) is designed to simulate macros in JavaScript. For example, you can use SweetJS to replace the function keyword with def.
