how can I optimize that code, my co-worker told me that this code returns true and false, I already did it but, he said it not correct and told that I need recheck! 

```
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    this.token = localStorage.getItem('JWT_TOKEN');
    if (!this.token) {
      return this.router.navigate(['mypage']);
    } else {
      return true;
    }
  }

```
