What is the role of NgModule in Angular?

• @NgModule is a decorator that defines a module.
• It declares which components, directives, and pipes belong to the module.
• It imports other modules needed for its components.
• It exports components/modules to make them available elsewhere.
• It configures services/providers scoped to the module.

Example:

@NgModule({

declarations: [MyComponent, MyDirective],

imports: [CommonModule],

exports: [MyComponent]

})

export class MyModule {}
