What are the best practices for using context in Golang?

In Golang, it's important to use context for managing deadlines, cancellations, and passing request-scoped values. Always pass context as the first parameter 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 is useful for operations that might hang.

What about using context for cancellation?

You can use context.WithCancel to create a cancellable context. Call the cancel function when you want to stop the operation.

Are there any common mistakes to avoid?

Yes, avoid storing context in global variables or passing it around unnecessarily. Always use it for the duration of a request.
