MongoDB:
MongoDB is a NoSQL database used in the MERN stack for storing data. The update operation in MongoDB involves modifying the values of one or more fields within a document in a collection.

Express.js and Node.js:
Express.js is a web application framework for Node.js. In the MERN stack, the server-side (back end) code, often built with Node.js and Express.js, handles the update operation. This involves defining routes and controllers that handle incoming requests to update data in the MongoDB database.

A typical update operation using Express.js may involve receiving an HTTP PUT or PATCH request with the new data from the client, processing this request on the server, and then updating the corresponding document in the MongoDB collection.
