Angular2: setTimeout only called once

I'm implementing functionality in Angular2 that requires the use of setTimeout.

My code:

  public ngAfterViewInit(): void {

    this.authenticate_loop();

  }



  private authenticate_loop() {

    setTimeout (() => {

      console.log(Hello from setTimeout);

    }, 500)

  }

setTimeout is started by ngAfterViewInit but the loop is only executed once, eg. Hello fromsetTimeout is only printed once.

Question: How can I change the code to make the setTimeout work?

 private authenticate_loop() {

    setInterval (() => {

      console.log(Hello from setInterval);

    }, 500)

 }

setTimeout will run just one time, unless you create another setTimeout.
