I am not able to display the array of elements values in html page.

I have selected values of json array of object, from this result I removed the duplicate category values, and that values convered to array of string. and I listed that array of element. But I don't know to display the forEach element in a ngFor loop in angular.

export class PreviewComponent implements OnInit {
public menus : any = [];
newuniq: any[][];

ngOnInit() {
 this.newmenuService.getProducts()
    .subscribe(resp=>{
      this.menus = resp;
    console.log("cart",this.menus)
    })
 const newuniq = [...new Set(this.menus.map(item => item.category
      ))];

 newuniq.forEach(function(element) {
      console.log("element",element);
      
    });

}

component.html {{newuniq}}
