[go-nuts] Sharing data via Mutex vs. Channel

Hi folks, somwhere on my golang journey ("don't k now where and when") I was teached that mutexes are very expensive and we should prefer to communicate over channels instead of working with mutexes. I trusted it until today. I explained it to our aprentice based on my knowledge and he asked
