如何获得数组第一个元素的作用域

Question

I'm using AngularJS and Firebase and I have the below which is fine

var myTeam = Teams.child(thisTeam);   
var myFixtures = myTeam.child("fixtures").startAt(now).orderByChild("date"); 

$scope.team = $firebaseArray(myTeam);                 
$scope.fixtures = $firebaseArray(myFixtures);

Now I want to get the first fixture coming up and everything seems to point at being able to get it with

var myNextFixture = myFixtures.limitToFirst(1);  
and then  
$scope.fixtures = $firebaseArray(myFixtures); 

but that doesn't return anything, what am I missing?
