Channels in Go

 Channels in Go

Channels are a fundamental part of Go's concurrency model. A channel is a communication mechanism that allows one goroutine to send values to another goroutine. Channels provide a way to synchronize the execution of goroutines and communicate between them.

Here's an example of creating a channel and sending a value over it:

ch := make(chan int)

go func() {

    ch <- 42

}()

val := <-ch

fmt.Println(val) // prints 42

In this example, we create a channel of type int using the make function. We then create a goroutine that sends the value 42 over the channel. Finally, we read the value from the channel and print it.

Channels can be used for many purposes, such as passing data between goroutines, signaling events, and implementing synchronization mechanisms.
