How can I use a cursor.forEach() in MongoDB using Node.js?

Question

I have a huge collection of documents in my DB and I\'m wondering how can I run through all the documents and update them, each document with a different value.

Answer 1

You can now use (in an async function, of course):

for await (let doc of collection.find(query)) {
  await updateDoc(doc);
}

// all done

which nicely serializes all updates.
