If you are ok paying. I think the frontendmasters.com has some brilliant introductions. I specidfically enjoyed the React course on it done by Brian Holt. Spends a lot of time on tooling as well which I think is really important long term. You will also get access to a course on d3.js by Skirley Wu(look her up) which will help you tie in react with d3. If you are short on time and dont want to spend time research the right material to stufy on this may help.
