What are some examples of using the Go context package?

Can you give me some examples of how to use the Go context package?

Sure! The Go context package is used for managing deadlines, cancellation signals, and request-scoped values. For example, you can create a context with a timeout like this: ctx, cancel := context.WithTimeout(context.Background(), 2 * time.Second).

What happens if the context times out?

If the context times out, any operations that are using that context should stop and return an error indicating that the context has expired.

Can I pass values through the context?

Yes, you can use context.WithValue to pass values. For example: ctx := context.WithValue(parentCtx, key, value).

Are there any best practices for using context?

Yes, some best practices include: always pass context as the first argument, avoid storing context in global variables, and use context only for request-scoped data.
