Angular is a robust, full-featured framework for building web applications developed and maintained by Google. It’s a complete rewrite of AngularJS and has become one of the most popular enterprise-level frontend frameworks.

Here’s what makes Angular powerful:

  • Component-based architecture: Organize your application into reusable, encapsulated components

  • TypeScript integration: Benefit from strong typing and object-oriented features

  • Dependency injection: Build services that can be injected where needed

  • RxJS integration: Handle asynchronous operations using observables

  • Comprehensive tooling: Angular CLI simplifies project creation, development, and deployment

A simple example of an Angular component:

// hello.component.ts import { Component } from '@angular/core'; @Component({ selector: 'app-hello', template: `  <h1>Hello, {{ name }}!</h1>  <button (click)="incrementCount()">  You clicked me {{ count }} times  </button> ` }) export class HelloComponent {  name = 'World';  count = 0;  incrementCount() {  this.count++;  } }

To fetch data from an API:

// data.service.ts import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; import { Observable } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class DataService { constructor(private http: HttpClient) {} getData(): Observable<any[]> {  return this.http.get<any[]>('https://api.example.com/data');  } }
