What are some examples of concurrency in Go?

In Go, concurrency is achieved using goroutines and channels. Would you like to see specific examples?

Yes, please provide a simple example using goroutines.

Sure! Here's a basic example:

package main

import (
    "fmt"
    "time"
)

func sayHello() {
    fmt.Println("Hello from goroutine!")
}

func main() {
    go sayHello() // Start a new goroutine
    time.Sleep(1 * time.Second) // Wait for goroutine to finish
}

This code starts a goroutine that prints a message.

What about using channels for communication?

Great question! Here's an example using channels:

package main

import "fmt"

func greet(ch chan string) {
    ch <- "Hello from goroutine!"
}

func main() {
    ch := make(chan string)
    go greet(ch)
    message := <-ch // Receive message from goroutine
    fmt.Println(message)
}

This code demonstrates how to send messages between goroutines using channels.
