Eventually, I will learn React properly, but I hurried through Wes Bos’ React tutorial earlier this year. It served as a great introduction with the secondary effect of increasing my awareness and understanding with JSX, Gulp and Firebase. The folks in the course’s slack channel are very helpful.
Overall, Wes has produced many videos on various WebDev topics and is highly regarded.
Caveat: I’ve been away from React for a few months, and if it has even been necessary, I don’t know if Wes has maintained the material inline with any changes to React.
