What are some common async patterns in Go?

What are some common async patterns in Go?

In Go, common async patterns include goroutines, channels, and the use of the sync package for synchronization.

Can you explain how goroutines work?

Goroutines are lightweight threads managed by the Go runtime. You can start a goroutine by using the go keyword followed by a function call.

What are channels used for?

Channels are used for communication between goroutines. They allow you to send and receive values, helping to synchronize execution.

How do I handle errors in async functions?

You can handle errors in async functions by returning an error value and checking it after the goroutine completes.

Are there any best practices for using async patterns in Go?

Yes, some best practices include avoiding shared state, using channels for communication, and properly handling goroutine lifecycles.
