How to remove the first element of an array in a mongodb (nodejs) entry?

Question

MongoDB

I have a field, how do I remove the first element of item_keys?

Answer 1

Browser prompt: "MongoDB remove first element from an array".
Result: https://docs.mongodb.com/manual/reference/operator...

db.collection.updateOne({ _id: ... }, { $pop: { item_keys:  -1 } })

Have you seriously waited 20 minutes for this?
