What is concurrency in Go and how can I implement it?

Concurrency in Go allows multiple tasks to run simultaneously. You can implement it using goroutines and channels.

Can you give me an example of using goroutines?

Sure! Here's a simple example:

package main
import (
    "fmt"
    "time"
)

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

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

What are channels and how do they work?

Channels are used to communicate between goroutines. You can send and receive values through them, ensuring safe data exchange.

Can you show me a simple example of using channels?

Absolutely! Here's a basic example:

package main
import "fmt"

func main() {
    messages := make(chan string)

    go func() {
        messages <- "Hello from channel!"
    }()

    fmt.Println(<-messages) // Receive message from channel
}
