Angular 2 setinterval() keep running on other component

Question

I have the following method in one component:

ngOnInit()
        {
            this.battleInit();
            setInterval(() => {
                this.bat         


        

Answer 1

ngOnInit() {
  this.battleInit();
  this.id = setInterval(() => {
    this.battleInit(); 
  }, 5000);
}

ngOnDestroy() {
  if (this.id) {
    clearInterval(this.id);
  }
}

this.id is an identifier returned by the setInterval that can be used to cancel the operation using clearInterval.
