### Run React App in Development Mode (npm start) Source: https://github.com/kutlugsahin/smooth-dnd-demo/blob/master/README.md The `npm start` command launches the React application in development mode. It automatically opens the app in your browser at `http://localhost:3000` and reloads the page upon code edits, providing immediate feedback for development. ```Shell npm start ``` -------------------------------- ### Eject Create React App Configuration (npm run eject) Source: https://github.com/kutlugsahin/smooth-dnd-demo/blob/master/README.md The `npm run eject` command is a one-way operation that removes the single build dependency from the project.
