Reusable Code - For Good or For Awesome!

What sets reusable JavaScript apart from other JavaScript? How can we
make our code developer-friendly, fast, robust & compatible?

The API is make-or-break when it comes to reusable code. It's the API
that lets other developers use your application, if it's difficult to
use then they won't get the most out of what you've written.

We'll analyse existing APIs, looking at where they fail and where they
succeed, looking at what patterns they use and how users react to
them.

By looking at the wins and fails in the real world, we can discover
what makes code a pleasure to use and reuse.
