Is there way to use interpolation inside *ngFor

<div *ngFor="let t of {{randomName}}"></div>

I want to pass the array name dynamically, i tried above code but i got error.

Thanks for answers but i have to update the question with my scenario

<div formArrayName="{{obj.key}}">
 <div *ngFor="let t of formGrp.controls.{{obj.key}}.controls"></div>
</div>

I am creating form array dynamically and it can have any name depending on schema. I am able to bind that dynamic name to formArrayName as it supports interpolation but i need same behaviour on loop also

It should be easy by using square brackets notation:

<div *ngFor="let t of formGrp.controls[obj.key].controls"></div>
                                      ^^^^^^^^^

<div *ngFor="let t of dynamicArr"></div>

What you can do is set the Array dynamically in your component. Rather than using string interpolation.

export class SomeClass {
   dynamicArr:[];  
   updateArr(){
     // some logic
   return this.dynamicArr = dynamic Array
   }
}

<div *ngFor="let t of getTheData()"></div>

getTheData is a method in your component that returns the data

Check the example here https://plnkr.co/edit/Ma66tJhpldYY4GuuM3uU?p=preview in the .component.ts
