it helps some times If what you are getting from fire base is an array of objects, then you can achieve this by using javaScript:
function search(value){
  var ret = "";
  yourFireBaseArrayObject.forEach(function(obj) {
       if(obj.roomNumber === value){
         ret = obj.roomEmail;  
         return;
       }
   }
   return ret;
 }

How do I get an array of objects from Firebase?

it helps some times When I get all items from a JSON table in Firebase, it returns them as object of objects. , You can order them into an array on the client-side.
var query = this.refJob.orderByChild('status').equalTo('Active'); 
var array = [];
query.on('value', (snap) => {
  snap.forEach((child) => {
     var item = {};
     item._key = snap.key();
     array.push(item));
  });
});

Ordering objects in firebase Array in ngRepeat using elements stored at a different location in the database

like below fixes the issue I want to order the objects in my array in the ngRepeat using values stored in firebase under a different thread. See code and images. I am currently using the following code, it doesn't give errors but neither does it order my objects according the the amount of votes: , I solved the problem using a function. See code below: In the HTML:
ng-repeat="for in For | orderBy: orderFunc | limitTo: 30"
$scope.orderFunc = function(element){
    order = -(dataVotes[element.ref].total) ;
    return order
}

Creating an Array of JS objects from Firebase

Hope this helps Create the mestaz array only once outside the loop not a new instance every iteration of the loop
var mestaz = []; /// create one array

for (var i = 0; i < keys.length; i++) {
  var k = keys[i];

  var mesto = {
    name: mesta[k].nazevmesta,
    lat: mesta[k].lat,
    lng: mesta[k].lng
  };

  // push each object to same array
  mestaz.push(mesto);

}

// log whole array after adding all of the elements in the loop
console.log(mestaz);

Firebase: How to get array back rather than objects

To fix the issue you can do I am making a call to get a list of books I have setup in firebase with this call , Go over the Object keys and convert to Array of Objects using map.
var obj = { a:  { b : 2 }, c:  { b : 2 } };

var arr_obj = Object.keys(obj).map(key => ({ [key]: obj[key] }));

console.log(arr_obj)
