? (documentRef = db
.collection('files')
.doc(refArray[0])
.collection('files')

.doc(refArray[6])
.collection('files')
.doc(refArray[7])
.collection('files')
.doc())
: (documentRef = db.collection('files').doc());

and this is my Web Code which can do same but only consume one line with path
const db = App.firestore()
const batch = db.batch()
const upd = ref.split('/')
upd.splice(0, 2)
const result = upd.join('/files/')
console.log(upd, 'AFTER SPLIT AND SPLICE')
let newRef = '/files/'
newRef = newRef.concat(result)
console.log(ref, 'REF ')
console.log(newRef, 'new REF ')
const TimeStamp = firebase.firestore.Timestamp.now()
const geoPoint = new firebase.firestore.GeoPoint(location.latitude, location.longitude)
const flEntity = { ...folderEntity }
const documentReference = db.collection(upd.length > 0 ? ${newRef}/files : 'files').doc()

my newRef variable is /files/doc.id/files/doc.id
