Understanding golang channel range... again

Wed, 27 Nov 2019 11:17:40 +0000

In a previous article, I tried to explain my understanding of go channels interaction with ranges. Turns out my explanation was probably not clear enough because here I am, nearly a year after, struggling to achieve pretty much the same exercise.

So here we go again, on a good old trial and error fashion progress.

The goal here is to retrieve channel messages that are pushed from go routines created in a for loop.

Understanding golang channel range

Here we go again with my golang self teaching, today with a topic I had hard time understanding correctly (and hope I actually did): range over channels along with goroutines.

First of all, let’s have a little reminder. We all know a goroutine live its own life and must be waited for at the main level, i.e. in this example:

package main

import "fmt"

func main() {
	go func() {
		fmt.Println("hello there")
	}()
}
