Switching from React to ReactNative?

Question

React

If I write a web application using React, will it be easy to translate it to ReactNative?
And if you use React when writing desktop applications using Electron, is it normal or not?

Answer 1

Translating is not a problem, the code will remain the same, only the markup will have to be changed - instead of html there are their own tags. The same situation with desktops, the transition without problems
