Next step to start writing javascript...

Having been through most of the JS deep dive here, and some other JavaScript lessons, as well as using some Javascript plug-ins, I have gotten to the point where I can use fairly simple 3rd party plugin's and make minor tweaks to existing code to do exactly what I need.

An example would be using the javascript elements that the twitter boostrap package has. I can set those up no problem.

The deep dive for me here showed me the roots of the language, but not how to put it all together to do some of the really cool stuff I know javascript can do!

However, I feel like I'm stuck on this plateau of actually writing custom JavaScript. I look at these plugins, and have know I couldn't have written it myself. And than I hear things like backbone.js or node.js and I do not really understand those yet.

How can I break this plateau? When does the 'ahh ha' moment hit and it starts making sense.

As of right now, I'd say I understand PHP better than I do JavaScript.
