What are Angular decorators and how do I use them?

Angular decorators are special functions that add metadata to classes, properties, methods, or parameters. They are used to define components, directives, services, and more.

Can you give me an example of a component decorator?

Sure! The @Component decorator is used to define a component. Here's a simple example:

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

@Component({
  selector: 'app-hello',
  template: '<h1>Hello, World!</h1>'
})
export class HelloComponent {}

What other decorators are commonly used in Angular?

Other commonly used decorators include @Injectable for services, @Directive for directives, and @NgModule for modules.

How do decorators improve code readability?

Decorators improve code readability by clearly defining the role and behavior of classes and their members, making the code more organized and easier to understand.
