Where can I find a description from the react.js library?

Question

React

If react.js is installed as an npm package, then \node_modules\react\lib\ libraries will come with it. But I haven't seen a description from her anywhere.
Tell me where to find the description of this library.

Answer 1

This is not a separate library, it is the react itself and is in the form expanded into modules. From there, some modules may come in handy separately in the application, for example, emptyFunction emptyObject and others, I have not seen descriptions since this is not the main usecase
