React App Build and Testing Instructions

To start a Create React App project, use the script in the project directory with the command: `npm start`. This will run the application in development mode and open it in the browser. Any changes made will trigger a page reload, and errors will be displayed in the console. To start the test runner in interactive mode, use `npm test`. For building the application for production, use `npm run build`, which bundles and optimizes React for performance, generating minimized files with hashed names. Your app is then ready for deployment. To eject from the default setup and customize build tools and configuration, use `npm run eject`. Note: this action is irreversible. The eject command removes the single build dependency and includes all configuration files and dependencies like webpack, Babel, and ESLint. For more details, refer to the documentation section.
