  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';
  
  myArray = [1, 2, 3, 4, 5, 6];
  
  addNew(){
    this.myArray.push(this.myArray.length + 1);
    console.log(this.myArray);
  }
}

Output:

[1, 2, 3, 4, 5, 6, 7]
[1, 2, 3, 4, 5, 6, 7, 8]
[1, 2, 3, 4, 5, 6, 7, 8, 9]

    {id: 2, name: "Vimal" },
    {id: 3, name: "Paresh" }
  ];
  
  addNew(){
    this.myObjArray.push({id: 4, name: "Vimal"});
    console.log(this.myObjArray);
  }
}

})
export class AppComponent  {
  name = 'Angular';
  
  myObjArray = [
    {id: 1, name: "Hardik" },
    {id: 2, name: "Vimal" },
    {id: 3, name: "Paresh" }
  ];
  
  addNew(){
    this.myObjArray.unshift({id: 4, name: "Vimal"});
    console.log(this.myObjArray);
  }
}

Output:

__proto__: Object
1: Object
