How do I handle errors in Go goroutines?

In Go, you can handle errors in goroutines by returning errors from the function and using channels to communicate them.

Can you show me an example of that?

Sure! You can create a goroutine that performs a task and returns an error through a channel. Here's a simple example:

func doWork(ch chan error) {
    // Simulate work
    err := someFunction()
    ch <- err // Send error to channel
}

func main() {
    ch := make(chan error)
    go doWork(ch)
    err := <-ch // Receive error from channel
    if err != nil {
        fmt.Println("Error occurred:", err)
    }
}

What if I have multiple goroutines?

You can use a slice of channels or a wait group to handle multiple goroutines. Collect errors from each goroutine and process them after all have completed.
