I am so new to JS that this is sort of over my head and would probably go over this at some time in the future. Promise. :) But a mini-review at the end of the video about what was discussed would be nice. Just the last few minutes about the topics, in a sort of bullet style points, also some simple code examples that you could add reference, like a gist and add an annotation on the video with the url. Also you could add to your description the time at which each topic is started so someone could jump over in the video.
