Is there a potential race condition here?

Working with Data

Say I have the following example doc:

{
  "name": "Jimmy Maxwell",
  "phone": "555-123-4567",
  "address": "123 Fake Street"
}

Say I have two independent operations: one that updates the phone number, and one that updates the address. These two operations are called concurrently (using an async library) at the same time:

db.person.updateOne({"name": "Jimmy Maxwell"}, {"$set": {"phone": "555-765-4321"}})
db.person.updateOne({"name": "Jimmy Maxwell"}, {"$set": {"address": "321 Maple Ave"}})

Is there a potential race condition such that either the phone or address won’t be set properly, or is it safe given that the updates only touch their respective fields?
