Angular.JS Quiz

Answer:

The key to both is assigning the result of the function to a variable.

To cleanup the timeout, just “.cancel()” it:

var customTimeout = $timeout(function () {
  // arbitrary code
}, 55);

$timeout.cancel(customTimeout);

The same applies to “$interval()”.

To disable a watch, just call it.

// .$watch() returns a deregistration function that we store to a variable
var deregisterWatchFn = $rootScope.$watch(‘someGloballyAvailableProperty’, function (newVal) {
  if (newVal) {
    // we invoke that deregistration function, to disable the watch
    deregisterWatchFn();
    ...
  }
});
