I'm looking a right way to iterate in firestore docs;

        this.globalCounters = firebase.firestore().collection('AnswersCounters').doc('Questions')

I found a way to do this with Object.keys() but I don't think this way is the right one.

        this.unsubscribe_globalCounters = this.globalCounters.onSnapshot(this.showAnswers) 


 showAnswers(querySnapshot){

    let snapshotData = querySnapshot.data();
    let answersCounters =[]
    Object.keys(snapshotData).map((i)=>{

        answersCounters.push({key:i,count:snapshotData[i]})

        })
}

It looks a bit chaotic and non-idiomatic, but should run. What's the problem? – Frank van Puffelen Apr 18 '18 at 03:53
it run, but I'm looking another way without Object.keys() – Manspof Apr 18 '18 at 07:54

That'd be `for (var key in snapshotData) {`. See https://stackoverflow.com/questions/684672/how-do-i-loop-through-or-enumerate-a-javascript-object – Frank van Puffelen Apr 18 '18 at 14:42
