typescript - Firebase Firestore get() async/await

Question

can anyone help me to "translate" this example in Typescript with async/await

console.log("start") 
var citiesRef = db.collection('cities');
var allCities = citiesRef.get()
    .then(snapshot => {
        snapshot.forEach(doc => {
            console.log(doc.id, '=>', doc.data().name);
        });
        console.log("end")
    })
    .catch(err => {
        console.log('Error getting documents', err);
    });

I tested some code but i think i do something wrong with the 'forEach' loop.

The result i want in console:

start
Key1 => city1
Key2 => city2
end

Result i get in some of my tests:

start
end
Key1 => city1
Key2 => city2

Thx in advance
