I have started to study React and I’ve tried tried a few resources here and there. I found a course at openclassrooms that does a good job introducing React to a beginner.
You will use react-create-app to set up a small project on your own machine. I like how they explain the basics and the structure of the app…They will also introduce you to JavaScript modules as well.
The course gets pretty complex at the end, but the beginning is excellent.
