This is the list I wish I had before starting my learning journey over 2 years ago. The best way to utilise this list would be to start with a course you like and sticking with it till the end. When you learn a new concept check the supporting documentation. Don't get intimidated if you don't understand everything, it's more to get you in the habit of reading documentation. After you have completed a course start building a project. Only when you can apply the stuff you have learnt can you say you know React.
There are both paid and free courses on this list and none of them are sponsored. I have tried or finished most of them and can vouch for their quality.
Youtube course - The Net Ninja : The net ninja is a great tutor to help you understand react. It covers the basics of React, Redux & React router. The series is a bit old but all the knowledge still applies today.
FullStackOpen : This is a web development course by the University of Helsinki, Finland. This covers content for both frontend and backend. You will learn React, Redux, Node js, Express, Mongo DB, Typescript & Graphql. Absolute gold standard if you want to learn full stack development from scratch.
Udemy course - Andrew Mead : Great teacher who goes in depth of various topics. Will teach you react, redux, react router, firebase, testing & hooks. The series is a bit old but a update is in works which should be out in a couple of months. The update will be free if you have already bought the course.
LevelUpTutorials : Great site if you need quick tutorials on react. Each series has about 25 videos 10-15 mins each and is a great resource if you want to know the basics and start quickly building on your own.
Create React App : If you build a new react app, make it using Create React App it handles a lot of complexity for you.
I hope this sets you on your journey of learning. If you need help with learning React you can join Goodhub it has a slack channel where people learn new languages, build projects and motivate each other. You can also DM me on twitter.
