var app = angular.module("app", []);

app.run(function ($interval) {
    console.log('This fiddle will self destruct...');
    
    var timer = $interval(function (count) {
        console.log('tick... ' + count);
    }, 500, 4, false);
    
    timer.then(function(res) {
        console.log("BOOM! " + res);
    });
});

Output:

This fiddle will self destruct...
tick... 1
tick... 2
tick... 3
tick... 4
BOOM! 4

The final result is the final count.
