How to learn faster?

I found the exact same thing Aljaž. JavaScript simply requires more time to learn - the concepts are more involved, and there's a lot more that's possible in JavaScript. My suggestion would be to accept the slower pace and focus on making sure you really understand what you're learning.

But if you really want to improve your pace... probably the best thing you can do is work on some actual projects. I don't mean professional ones, but just things you come up with yourself. Just make a simple website that uses some JavaScript, maybe a photo gallery for example. A day (or even an hour or two) spent working on non-Treehouse projects here and there will mean you can process the Treehouse content a lot quicker. So you're taking less time to learn overall, plus you have some projects you can show off in a portfolio!

What helps me a lot is trying it myself, like Bianca already said on a own small project. There you can play around without messing something up and build the roots in your mind.
