Wanderlust

I have just finished the Wanderlust project in the requests/intermediate JavaScript section of Web Development, and I have a few questions. There was a lot of jQuery in this project and I’m wondering if it would be beneficial for me to take a break from the Web Development path and take the jQuery course before continuing? Or will that be something I pick up on later in the career path? I feel like I finished the project not knowing a lot of the things that were going on. Any info on the subject would be appreciated.
