React kurulumu için öncelikle bilgisayarınıza node JS kurmanız gerekmektedir kurduktan sonra cmd ile ilgili klasöre gidip kurumu yapabilirsiniz

C:\Users\hasan.aylas>e:

E:\>cd react

E:\react>create-react-app firsrt

Dedikten sonra bekleyelim

Creating a new React app in E:\react\firsrt.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts…

sonuc olarak su gelir

Success! Created firsrt at E:\react\firsrt
Inside that directory, you can run several commands:

npm start
Starts the development server.

npm run build
Bundles the app into static files for production.

npm test
Starts the test runner.

npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

cd firsrt
npm start

Happy hacking!
