#56 Update documents in a collection | Getting Started with MongoDB | A Complete NODE JS Course

We learned how to insert and fetch documents from a collection. In this lecture, let's learn how to update an existing document in a collection. For updating documents, we have two methods:

* updateOne() - updates one document at a time
* updateMany() - updates multiple documents at a time

These two methods are supported by all major drivers available for MongoDB.

Is it possible to update a document to remove a key? For example: update {name: "john", age: 32, gender: "male"} to {name: "john, age:32}
