  • You can use array:any[] or create a class e.g product containing the objects in your array and declare array:product [] Commented Sep 4, 2020 at 16:07

First create interface

export interface MainObject {
  myArray: {name: string, available: boolean}[];
}

Then use that interface in component.

export class MyComponent {
   MyMainObject: MainObject = {} as MainObject;

constructor() {
    this.MyMainObject.myArray.push({ name: 'name', available: true });
    console.log(this.MyMainObject);
  }
}

//Simply declare Object like inside class

    MyMainObject: {
    myArray : []
    };

//nd push value dynamically like inside any method

    if(condition){
    this.MyMainObject['myArray'].push(
    {name:string, available:boolean}
    )
    }
