In Go, JSON unmarshaling is the process of converting JSON data into a Go data structure, such as a struct or a map. The encoding/json package provides the Unmarshal function to perform this operation. Unmarshaling allows you to take JSON formatted data and populate a Go data structure with it, enabling you to work with the data in a type-safe manner within your Go program.

A graceful shutdown in the context of web servers and applications refers to the process of shutting down the application in an orderly manner, ensuring that all current operations are completed before the application stops. During a graceful shutdown, the server stops accepting new requests but continues to process the ongoing requests until they are completed, or a specified timeout is reached. The main goals are to minimize data loss, ensure consistency, and not disrupt users more than necessary.
