This will install the Angular CLI (Command Line Interface) globally on your system. You can then use the CLI to create a new Angular project.

Method 2: Using yarn

You can install Angular using yarn (a package manager for JavaScript) by running the following command in your terminal:

yarn add @angular/cli

This will install the Angular CLI globally on your system. You can then use the CLI to create a new Angular project.

Run the following command to create a new Angular project:

ng new my-app

Replace my-app with the name of your project.
