As well as cat videos YouTube has an incredible amount of high-quality free web development videos. This a list of channels I subscribe to with all sorts of useful videos.

  By Mattias Petter Johansson, mpj for short. One of the best channels to watch for JavaScript, highly recommended.

  Update - As of 20th April 2018 mpj along with Data David are taking over the DevTips channel - so if you like Fun Fun Function, it is worth giving that a look as well.
