How do applications usually write in react.js?

Question

JavaScript

I'm interested in a few things. Let's say there is a site with a bunch of interface, how is the development process divided into react? Is it first laid out in html and then everything is split into react components or is there some other way? (I think I answered this question myself, but there may still be something else).
Also, does it make sense to use react not for single page sites?

Answer 1

In short, it's easier to just start writing react and understand that it's simple and cool.

Answer 2

or is there some other way

yes, immediately layout in jsx

Answer 3

You can vice versa - make a draft version, divided into components - and then hold out the layout
