  6. npm i -D @babel/core babel-loader @babel/preset-env @babel/preset-react: Installs Babel tools. These tools make your JavaScript code compatible with older browsers.
  7. npm i -D react react-dom: Installs the React library and the ReactDOM module.
  8. npm i -D tailwindcss: Installs the Tailwind CSS library.
