){}}

An element access expression should take an argument

Solution

  • You got this error because you are trying to declare your variable after import statements, not into the class.
    You should declare it as below:

    //import statements
@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"],
})
export class AppComponent {
  category: category[] = [];
  constructor() {}

  ngOnInit() {}
}
