To install react, we need two things. 1. Node.js , 2. npm 3.yarn
First, we go to node.js website. and here is a link.
and install what you want.
and you install npm.
and here is a link.
but, you install node.js first, it also include npm, so you don't need to install npm seperately.
Now, you can install ReactJS!! Because it based on node.js.
but i recommand also install yarn, because it help us to activate react project.

First, open terminal app, and type this code.
npm install -g create-react-app
and finish process, move directory where you want to create react project and type this code

and this is finish window.
then, you open chrome(or any good web browser) and type http://localhost:3000/
