I recently ran across this excellent slide deck from K. Adam White on evolving your JavaScript with BackBone.js. It’s a really great deck that I highly recommend you fully digest. It’s simple enough for people not yet well versed in such things but want to learn, but also has plenty of meaty content for those that are. I’ll try and update this post once the talk from WordCamp Providence 2013 goes on WordCamp.tv.
Also check out his talk last year at the same event that’s like a precursor to this talk.
