How can I manage context in advanced Go applications?

How can I manage context in advanced Go applications?

In Go, you can manage context using the context package. It allows you to pass deadlines, cancellation signals, and request-scoped values across API boundaries.

Can you explain the difference between Background and TODO contexts?

Sure! context.Background() is typically used as the top-level context, while context.TODO() is used when you're unsure which context to use. Both are non-cancelable.

How do I handle cancellation in goroutines?

You can use a context.Context with a cancellation function. When you call the cancellation function, it signals all goroutines using that context to stop their work.

What are some best practices for using context in Go?

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