Meteor methods are asynchronous, you can get the result by many way.

Using npm module fibers (The other answer are explaining it very clearly).

There are some other way w/o using npm module :

Via Session variable :

    Meteor.call('myMethod',args, function(error, result) { 
  if (error) { Session.set('result', error) } // Note that the error is returned synchronously 
  else { 
    Session.set('result', result) // Using : Session.get('result') will return you the result of the meteor call !
  }
});

Or Via template variable :

    Template.hello.onCreated(function helloOnCreated() {
  // counter starts at 0
  this.message = new ReactiveVar(0);
});

Template.hello.helpers({
  message() {
    return Template.instance().message.get();
  },
});

Template.hello.events({
  'click button'(event, instance) {
    Meteor.call('myMethod', args, function (error, result) {
      if (error) { Template.instance().message.set(error); }
      else {
        Template.instance().message.set(result);
      }
    })
  },
});

Hope it will help !
