Explain Angular 2+ ngModule

@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})

• A module is a class decorated with @NgModule. It serves as a registry (aka container) for all the components, pipes, directives and providers in your application.
• An import is what you put in the imports property of the @NgModule decorator. It enables an Angular module to use functionality that was defined in another Angular module.
• An export what you put is the exports property of the @NgModule decorator. It enables an Angular module to expose some of its components/directives/pipes to the other modules in the applications. Without it, the components/directives/pipes defined in a module could only be used in that module.

• Providers

  This will include the services created.

  Bootstrap

  This includes the main app component for starting the execution.
