@NgModule({
 imports:      [ BrowserModule, ButtonModule ], // Registering EJ2 Button Module
 declarations: [ AppComponent ],
 bootstrap:    [ AppComponent ]
})
export class AppModule { }

    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
