Answer 1

Below is the test code and it simply works :

app.component.ts

import { Component } from '@angular/core';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {

  obj : any = ['test1', 'test2', 'test3'];

} 

app.component.html

{{ obj |  json }}

browser output

[ "test1", "test2", "test3" ]
