Yarn: A Fast and Reliable Package Manager for JavaScript

Yarn is a popular package manager for JavaScript that aims to simplify the development process of web applications. It allows developers to manage dependencies, install packages, and quickly build and deploy their projects.

Creating a React app with Yarn

To create a new React app with Yarn, you can use the create-react-app command. Here's an example:

yarn create react-app my-app

This will create a new directory called my-app in your current working directory and set up a basic React app with all the necessary dependencies.

Running a React app with Yarn

After creating a new React app with Yarn, you can run the app using the following command:

yarn start

This will start a development server and open your app in the default browser. Any changes you make to your app will automatically reload the page, making it easy to test and iterate on your code.
