<h1>This is simple creating component Example - ItSolutionStuff.com</h1>

import { Component, OnInit } from '@angular/core';
   
@Component({
  selector: 'app-favorite',
  templateUrl: './favorite.component.html',

import { BrowserModule } from '@angular/platform-browser';
  
import { AppComponent } from './app.component';
import { FavoriteComponent } from './favorite/favorite.component';
   
@NgModule({
  declarations: [
    AppComponent,
    FavoriteComponent
  ],
  imports: [
