To run this project type
ng serve
this will run the project on localhost:4200/
open the URL in the browser.
You will see the following output

Adding Your own Content

To change the above content goto

src->app->app.component.html

remove all content.

then put <h2>{{title}}</h2>

Then check the browser.

Adding More Content

It will show the Title name of your project.

Adding data to app.component.html

To add static content we can directly write in app.component.html

To add dynamic content you have to add content in app.component.ts

We added title description and author in class AppComponent as below

  import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'My First App';
  description="This is my first app in angular";
  author="Manish";
}

in app.component.html

{{title}}
{{description}}
created by {{author}}

To access app.component.html we use interpolation.

It will produce the following output
