create a rune channel in go

To create a rune channel in Go, we first need to understand what are channels and runes.

Channnels are a way of communication and synchronization between goroutines in Go. They are typed, which means we can define the type of data the channel will transmit.

Runes, on the other hand, are a built-in type in Go that represents a Unicode character. They are represented by the rune keyword and are expressed in single quotes.

To create a rune channel, we need to define a channel with the type chan rune. Here's an example:

main.go
package main

import "fmt"

func main() {
    // Creating a rune channel
    rc := make(chan rune)

    // Starting a goroutine to send runes to the channel
    go func() {
        for _, r := range "Hello world" {
            rc <- r
        }
        close(rc)
    }()

    // Receiving runes from the channel
    for {
        r, ok := <-rc
        if !ok {
            break
        }
        fmt.Printf("%c", r)
    }
}

In the example above, we created a rune channel named rc using the built-in make function. We then started a new goroutine using an anonymous function that sends the rune values of the string "Hello world" into the channel. Notice that we close the channel after we finish sending all the values.

Finally, we loop over the channel and print each rune received from the channel.

This is a simple example, but it demonstrates the basics of creating and using a rune channel in Go. By using channels and goroutines, we can achieve concurrency and easily communicate between different parts of our Go program.
