Serving the project
Angular CLI provides a complete tool-chain for developing front-end apps on your local machine. As such, you don’t need to install a local server to serve your project — you can simply, use the ng serve command from your terminal to serve your project locally.
The application will start serving in the root http://localhost:4200
