gAngular2 setHow to not check component value change in setInterval

I'm creating an auto-scrolling function on the screen, but it becomes very heavy because the value change check is performed in setInterval.
Auto-scrolling does not change the value of the component, so you do not need to check the change check.
Are there any setInterval functions that do not perform change checks?

You should be able to use the runOutsideAngular method in the NgZone class.Obtain an instance of NgZone in the Dependency Injection of the component before using it.

Sample

export classSomeCmp{
  constructor(privateZone:NgZone){}

  ngOnInit(){
    This.ngZone.runOutsideAngular()=>{
      setInterval (()=>{})
    });
  }
}
