What Is Angular CLI? 
The Angular CLI (Command Line Interface) is a tool to initialize, develop, scaffold and maintain Angular applications.
The Angular CLI (Command Line Interface) is a set of tools that is used to initialize, develop, generate files, scaffold, and test and maintain Angular application.

You can use CLI commands to generate an app, the default AppModule is as follows –
ng new yourApp

The above CLI command is used to create a new Angular project and this CLI command automatically creates several folders and files which are necessary for project development, testing, and configuration and so on.

To use  Angular CLI, we need to install it first and it should be installed globally in your machine.

npm install -g @angular/cli

Example –  CREATE your project directory as like below
F:\AngularTestApp\DemoApp>npm install -g @angular/cli
C:\Users\Anil\AppData\Roaming\npm\ng -> C:\Users\Anil\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng
`-- @angular/cli@1.5.0
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\@angular\cli\node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
