Iím new to javascript and Iíve learned that the (standard) way to include javascript from a file which is separate to your html file is like this:

<script type="text/javascript" src="external.js"></script>

But this means that all my javascript code must be contained in one single massive file.

But itís easier to navigate and debug a small javascript file, i.e. easier to develop js code in multiple small .js files, instead of the single massive Ďexternal.jsí indicated above.

So how can I include multiple files of javascript code?

Do you need a tool like Aptana?
