What is the difference between react and react native?
At present, I just know, I don’t know very well, and the company’s project inside is not used either. I want to learn more about it. Which is better to learn and from which aspects

I have used react, but I have not used react native. It is suggested to find an introductory tutorial first, then study the api documents carefully, find a good and simple example written by others on github to learn, and then write a small demo to practice my hand.
