When I open console of Chrome 14 and type...

require (or require(), if that matters)

I get: ReferenceError.

This means that JavaScript doesn't have that function by default, right? At least on web browsers.

Why I'm talking about that?

I needed Markdown parser for JavaScript.

What to do?

I, as usually, opened GitHub and searched for it. The first results that matched my needs was this and this.

Usually (I'm not that good with JavaScript) I include script I want to use before my code using <script /> tag and then... well - use it. But this time I don't get what's happening... :(

Usage for #1 script:

var input = # HeadingnnParagraph;

var output = require( markdown ).toHTML( input );

print( output );

Usage for #2 script:

var marked = require('marked');

console.log(marked('i am using __markdown__.'));

Where does that require() came from? Thanks in an advice! :)
