Talk comments

I always find this topic very interesting, and the approach in the talk is very step-by-step. I do feel that some of the concepts (like Promises) are quite abstract, and could use a little more explanation, but as a whole the presentation + demo show how elegant but powerful the end-result can be.

A tip I'd like to give the speaker is to just duplicate slides if there is a reference to some code that has already passed. Moving back-and-forth through the deck can get confusing, and I feel that adding some slides twice will keep the presentation moving forward, even when you're looping back to a previous concept to show how things tie together.
