Before starting with the installation of Angular CLI, let’s first get fully acquainted with it.
Angular CLI is a command line interface that is used to Scaffold and build angular applications using node.js style modules. It helps in creating Angular applications, from scratch as well as adding new elements in an existing Angular application. After installing Angular CLI, you will be able to use all of the ng commands. These commands can save us a lot of time since it practically helps in creating and running projects in a matter of minutes. Some of these commands are listed below:

ng serve –open
This command is used when you want to open your project in a web browser.
When we use serve command without specifying the port like in previous command, the project runs on 4200 port by default. This command is used when we want to run the project on a specified port. (In this case, port 4201)
To compile your Angular project into an output directory
