Answer 1

First solution, the Angular way :

getTopLiked() { 
  this._dashboardService.getTopPosts()
    .subscribe(res => { 
      // Get your data in your component's variable
      this.data = res.json();
    });
}

In your HTML

<div *ngIf="data">
  <div *ngFor="let liked of data.topLikedMedia">
    <p>ID : {{liked.id}}</p>
    <!-- And you do every other field like that -->
  </div>
</div>

Second solution, the old Javascript way

getTopLiked() { 
  this._dashboardService.getTopPosts()
    .subscribe(res => { 
      this.createMarkup(res.json());
    });
}

createMarkup(data: Object) {
  this.markup = '';
  for (let liked of data.topLikedMedia) {
    this.markup += `<p>ID : ${liked.id}</p>`;
    // add the other fields like that
  }
}

In your HTML

<div *ngIf="markup">
  <div [innerHTML]="markup"></div>
</div>
