How does CSP work in Go?

Can you explain how CSP works in Go?

CSP, or Communicating Sequential Processes, is a concurrency model used in Go. It allows goroutines to communicate via channels, enabling safe data exchange.

What are goroutines and how do they relate to CSP?

Goroutines are lightweight threads managed by the Go runtime. In CSP, goroutines communicate through channels, which helps avoid race conditions.

Can you give me an example of using channels in Go?

Sure! Here's a simple example:

package main

import (
    "fmt"
)

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

    go func() {
        ch <- "Hello from goroutine!"
    }()

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

This code creates a channel, starts a goroutine that sends a message, and then receives it.

What are some common pitfalls when using CSP in Go?

Common pitfalls include forgetting to close channels, which can lead to deadlocks, and not handling errors properly when receiving from channels.
