Confusion about how the promise returned by $interval works compared to $timeout in Angular

Question

I\'m having an issue understanding how the promise returned by $interval works in Angular.

Let\'s say in the following example, we have a simple \"api\" factory with a

The only thing you can do with the promise returned by $interval is cancel it (to stop its execution):

var handle = $interval(someFunc, 1000);
...
$interval.cancel(handle);

Your code should probably look like:

app.controller('appCtrl', function($scope, $interval, api) {
    $interval(function() {
        console.log(api.getStuff());
    }, 1000);
});

To be fancy and see everything working together:

app.controller('appCtrl', function($scope, $interval, $timeout, api) {
    var handle = $interval(function() {
        console.log(api.getStuff());
    }, 1000);

    $timeout(function() {
        $interval.cancel(handle);
    }, 5000);
});
