What are goroutines and how do they relate to asynchronous programming?

What are goroutines in Go programming?

Goroutines are lightweight threads managed by the Go runtime, allowing concurrent execution of functions.

How do goroutines differ from traditional threads?

Goroutines are more efficient than traditional threads; they use less memory and are multiplexed onto fewer OS threads.

Can you explain how to use goroutines for asynchronous programming?

You can use goroutines to perform tasks concurrently, and channels to communicate between them, enabling async behavior.

What are some best practices for using goroutines?

Best practices include managing goroutine lifecycles, using channels for synchronization, and avoiding race conditions.
