Is there a difference between React and React Native?

Question

React

Hello, today I was visited by a question on React, I want to start learning it and I think if I make a frontend for sites on React.js, can I use the same code for React Native?
Or if they are different, will it be difficult to make an application on React Native after the frontend for sites?

Answer 1

You can't use the same code as the components you want to use in React Native have different names. For example, in React Native there is no div , instead View is used, etc. But you can use actions.
After six months of working on React js, I started to understand React Native and the process is not very fast. It took about 3 months to adjust.
