Callback to $interval function

Question

How can I make sure the function runAfterLoopFinishes() runs after the $interval has finished? Right now it runs immediately after loop is first defined.

var loop = $interval(function () {
  // Do something great 10 times
}, 1000, 10);

// To run after looping
runAfterLoopFinishes();

Answer 1

$interval returns a promise.

var loop = $interval(function () {
  // Do something great 10 times
}, 1000, 10);

loop.then(function(){
  // To run after looping
  runAfterLoopFinishes();
}

An $interval promise will be notified after each iteration, but only resolve after the last.
