# Create a new React app .
Create React App is the CLI based tool and is the best way to start building a new single-page application in React.

It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production. You’ll need to have Node >= 14.0.0 and npm >= 5.6 on your machine.
## Quick Started

npx create-react-app my-app
cd my-app
npm start

or you can used yarn instead of npm like :
`yarn create react-app my-app`

## Output :
my-app
