What is your experience with using contexts in your projects?

In my Go projects, I actively used the context package to manage operation timeouts and request cancellations. For example, when working with HTTP requests or databases, I created a context with a timeout to prevent hanging or resource leaks.

Example of using a context with a timeout:

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

result, err := db.QueryContext(ctx, "SELECT * FROM users")
if err != nil {
    // handle error
}

I also used contexts to pass metadata between application layers, such as request identifiers for logging and tracing. This helps make the code more manageable and responsive to operation cancellations.
