Can Golang read the room?

Sometimes you want a function to be able to read the room, to get context about what is going on. For instance, if a certain function exits, you want all sub-processes to complete as well. Well, golang can’t read body language but it does have a context package. This package lets your code carry cancellation signals, deadlines, and request-scoped values across API boundaries and down into goroutines.

Key aspects of Go’s context:

Cancellation Signals:

A context.Context can carry a cancellation signal. When a context is canceled, all goroutines that are listening on its Done() channel will be notified, allowing them to gracefully stop their operations. This is crucial for resource management and preventing goroutine leaks.
