I have a Node.js and Firebase project.
How can I update a field in an array which already exists?
Seems out that Firebase has only two array operations - arrayUnion and arrayRemove.
Say I have to update currency in BRSR. How do I do that?

You will have to read the document, make changes to the array in memory, then write the document back to its original location. – Doug Stevenson May 13 '22 at 05:01
