Is There A Way To Change A Value In All Documents On Firestore?

I'm a beginner creating an mobile app with react-native and firebase. I have a value stored in many documents and i want to update the value in all the documents i tried with .wher

Solution 1:

Firestore doesn't provide a way to update documents in bulk based on their current values. There is no SQL-like "update where" type of syntax. You'll have to first query and read all the documents you want to change, then update them with their new values.
