Identifying & Printing an object within an object - Angular

Question

I have a JSON in the following format:

{
    key: value,
    key: value,
    key: {
       key: value,
       key: value
    }
}

I want to print these key values out to my page using Angular's ngIf to identify if the value is a string or another object. I tried using typeof but it gives me an unresolved variable error in Webstorm.

How do I know that the value is an object and that I need to go in and take key values from in there?

I am using Angular 6 & Webstorm IDE.

You can create a function to get that value.Take a look at this demo

In component.ts:

checkType(data){
  return typeof(data)
}

In html:

<div *ngIf="checkType(data.k1) === 'string'">
  I am string
</div>
