Angular is a client-side TypeScript based, front-end web framework by Google. Angular 8 is a great, reusable UI (User Interface) framework for the developers which help in building Single Page Applications. Generally, all the angular 2+ projects or applications are referred to as Angular applications. The earlier version is called Angular.js and angular is a complete re-write of Angular.js which comes with rich and useful features.

Approach:

• In order to know the version, first, we need to import 'VERSION' from '@angular/core'.
• The reason for importing this is that it is an object which contains properties that we can use to know the version.
• After importing it now access the version using the 'full' key from the imported Version.
• After retrieving the value assign it to a variable and then using a string interpolation display in the HTML file.
• Once you are done with the above implementation, start the project.

Code Implementation:

1. app.component.ts:

   import { Component, VERSION } from '@angular/core';
   
   @Component({
     selector: 'app-root',
     templateUrl: './app.component.html',
     styleUrls: [ './app.component.css' ]
   })
   
   export class AppComponent  {
     version = VERSION.full;
   }
   

2. 
   app.component.html:

   <h2> Welcome to GeeksforGeeks </h2>
   
   <p> The version of the App is : {{ version }} </p>
   

3. 
   app.module.ts:

   import { NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   import { AppComponent } from './app.component';
   
   @NgModule({
     imports:      [ BrowserModule ],
     declarations: [ AppComponent ],
     bootstrap:    [ AppComponent ]
   })
   export class AppModule { }
   

Output:
 

Note: My version number is 6 and hence it is displaying as 6.
