What is the primary purpose of Angular in web development?

Component Example

Here's a simple example of a component in Angular:

typescript
import { Component } from '@angular/core'; @Component({ selector: 'app-my-component', template: ` <h1>Hello, World!</h1> ` }) export class MyComponent { // empty for now }

This component creates an HTML element with the selector app-my-component and displays "Hello, World!" when rendered. 📝

Custom Directive Example

Here's an example of a custom directive in Angular:

typescript
import { Directive, Input } from '@angular/core'; @Directive({ selector: '[appHighlight]' }) export class HighlightDirective { @Input() highlightColor: string = 'red'; constructor() {} highlight(isReverse: boolean) { if (isReverse) { this.elementRef.nativeElement.style.backgroundColor = this.highlightColor; this.elementRef.nativeElement.style.color = 'white'; } else { this.elementRef.nativeElement.style.backgroundColor = 'white'; this.elementRef.nativeElement.style.color = this.highlightColor; } } constructor(private elementRef: ElementRef) {} }

This custom directive takes an input highlightColor and allows you to dynamically change the background and text color of the selected element. 💡
