How do I handle errors in concurrent Go applications?

In Go, you can handle errors in concurrent applications by using channels to communicate errors from goroutines back to the main routine.

Can you give me an example of how to implement that?

Sure! You can create a channel for errors and send any errors from your goroutines to that channel. Then, in your main function, you can listen for errors from that channel.

What if I have multiple goroutines? How do I wait for all of them to finish?

You can use a sync.WaitGroup to wait for all goroutines to finish. Increment the WaitGroup counter before starting each goroutine and call Done() when a goroutine finishes.

Is there a way to handle timeouts for these goroutines?

Yes, you can use the context package to set a timeout for your operations. This way, if a goroutine takes too long, you can cancel it.
