I'm trying to create a filter for my application It will filter by the datas' category, but I also want to sort them by its rating, higher rating will be on the top. I wrote the following code, but the orderby() function having issue.
const snapshot = await firebase.firestore().collection('Locations').where(
"category", "==", type).orderBy("rating").get();
if (snapshot.empty){
console.log('No matching documents');
return;
}
snapshot.forEach(doc=> {
locList.push(doc.data());
})
and here is my firestore data look like

To sort values from largest rating to smallest rating, specify the ordering as descending. Change the orderBy
function to:
.orderBy('rating', 'desc')
