If the new React-Router v4 and its associated documentation are any indication, this course series will probably be good. I learned most of these concepts myself, through tons of trial and error, so the course is likely worth the time savings.<p>As an aside, I was one of the people that was really upset with react-router's churn. But v4 is really good, and I'm glad they've learned their lessons and put out a really good router implementation.
Really excited to dig in on the content and appreciate to have such a high quality course for free.<p>I wanted to give some feedback of my impressions so far. The quality of the content is great, however the quality of the audio in the videos is not so much. It sounds like the lecturer is speaking so that he doesn't disturb people in the next room or something, and kind of mumbles over the words, which is a bit distracting to listen to. The content would benefit from him projecting his voice more as he speaks.
This is my second pass at the Fundamentals course and it's great the way they've updated it with the latest conventions (e.g. using es6 class syntax, webpack 2, React Router 4, and more).
