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 explain what goroutines are?

Goroutines are lightweight threads managed by the Go runtime. They allow you to run functions concurrently.

How do I use channels for communication between goroutines?

Channels in Go are used to communicate between goroutines. You can create a channel using make(chan Type) and use <- to send and receive messages.

Can you provide a simple example of using goroutines and channels?

Sure! Here's a simple example:

package main

import (
    "fmt"
    "time"
)

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

    go func() {
        time.Sleep(2 * time.Second)
        ch <- "Hello from goroutine!"
    }()

    msg := <-ch
    fmt.Println(msg)
}
