What are the best practices for using context in Go?

In Go, it's important to use context for managing deadlines, cancellations, and request-scoped values. Always pass context as the first argument to functions.

Can you explain how to handle timeouts with context?

Sure! You can use context.WithTimeout to create a context that automatically cancels after a specified duration. This helps prevent hanging operations.

What about using context for passing values?

You can use context.WithValue to pass request-scoped values, but be cautious as it can lead to tight coupling. Prefer using explicit parameters when possible.

Are there any common mistakes to avoid?

Yes, avoid using context for passing optional parameters or for global state. Also, never store context in a struct or use it after the request is done.
