Call a Javascript function every 2 second continuously for 20 second.

var intervalPromise;
$scope.startTimer = function(fn, delay, timeoutTime) {
    intervalPromise = $interval(function() {
        fn();
        var currentTime = new Date().getTime() - $scope.startTime;
        if (currentTime > timeoutTime){
            $interval.cancel(intervalPromise);
          }                  
    }, delay);
};

$scope.startTimer(hello, 2000, 10000);

hello(){
  console.log("hello");
}
