Angularjs 10 $digest() Iterations Reached

I have code like this: $scope.flags = []; $scope.$watch('selectedFilter', function() { for (var i = 0; i < 2; i++) { $scope.flags.push(i);

Solution 1:

One thing I want to point out is when you watch the change of a list, you should set the 3rd parameter to true.

$scope.$watch('flags', function (oldval, newval) {
    if (oldval != newval) {
        console.log("hello");
    }
}, true);
