Why Backend if there is ReactJS?

Why Backend if there is ReactJS ?.

I probably just have a wrong understanding of the concept of ReactJS on this and I'm asking.

Answer 1

React is not frontend, is it? it’s not very convenient to use api on react, it’s not designed for this, it’s for manipulating the virtual DOM. In principle, you can organize an api on react, but it will look at least strange and not on ReactJS, but on React (the one under nodejs)

Answer 2

All web (and not only) development is divided into a client and a server (they are also called frontend and backend, respectively). Frontend is what every user has. There are many such programs. The backend is a server where the client (frontend) accesses to receive any information and transfer it from the client for further processing / saving.
ReactJS is a user interface rendering library. You can use it both on the frontend (directly rendering div/span/a/etc. to the browser), or on the backend to "draw" html into a string and pass this string to the frontend for subsequent rendering in the browser.
How is React different from the backend? About the same as sweet from soft.

Answer 3

You won’t believe it - for centralized storage of all data of the site / application / service / anything))) 00
And the react conveniently and quickly draws to the visitor what the backend sends
