NodeJS Express Async issue

I have this function which gets some data from my database but i'm having a trouble calling the function and getting the proper response

  function getEvents()
  {
    var x = [];
    var l = dbCollection['e'].find({}).forEach(function(y) {
    x.push(y);
  });

 return x;
});

and another function which calls this function but it always returns undefined. How can i make the function wait till mongoose has finished filling up the array?

Thanks for the help!
