What advantage is there in using the $timeout in AngularJS instead of window.setTimeout?

Question

I had a suggestion to implement a timeout like this:

  $timeout(function() {

    // Loadind done here - Show message for 3 more seconds.
    $timeout(functi         


        

Answer 1

AngularJS modifies the normal JavaScript flow by providing its own event processing loop. This splits the JavaScript into classical and AngularJS execution context. Only operations which are applied in the AngularJS execution context will benefit from AngularJS data-binding, exception handling, property watching, etc.

By using the AngularJS $timeout service, the wrapped setTimeout will be executed in the AngularJS execution context.
