How does the context package in Go affect performance?

The context package in Go is designed to carry deadlines, cancellation signals, and other request-scoped values. It can improve performance by allowing goroutines to be canceled when they are no longer needed, thus freeing up resources.

Can you give an example of how to use it effectively?

Sure! You can create a context with a timeout using context.WithTimeout. This way, if a request takes too long, it can be canceled automatically.

Are there any performance drawbacks to using it?

While the context package is generally efficient, excessive use of context can lead to increased memory usage and complexity in managing goroutines.

What are some best practices for using the context package?

Best practices include passing context as the first parameter in function signatures, avoiding storing context in global variables, and using it only for request-scoped data.
