When using AngularJS's $timeout, what's the default delay?

Question

On the remarkably brief AngularJS $timeout documentation page, the 'delay' argument is stated as optional. When using $timeout without specifying a delay, I note that a delay is still applied.

Can anyone tell me how much time is allotted for the delay when the argument is left implicit?

Answer 1

When $timeout delay is omitted, it defaults to 0. However, the block of code contained in it is executed after the DOM has been manipulated by Angular. See response to AngularJS $evalAsync vs $timeout

Answer 2

My understanding is that a delay of '0' means that it will be picked-up as part of the next run of the event loop. That's an especially short but indeterminate amount of time.

Answer 3

It's immediately executed, the default would be zero. Here is a jsfiddle showing it: http://jsfiddle.net/dgarlitt/rqs3p/1/

angular
    .module('myApp',[])
        .controller('MyCtrl', function($scope, $timeout) {
            $timeout(function() {
                $scope.name = 'World';
            });
        });

Answer 4

The default delay is 0. The documentation has been updated since.
