Is it OK to leave a channel open?

Question

Is it OK to leave a Go channel open forever (never close the channel) if I never check for its state? Will it lead to memory leaks? Is the following code OK?

Answer 1

Go is garbage collected, so you don't really have to 'free' anything.

There is possibility to close channels, but it's mostly used as - close(channel) - tell the goroutine (or main program) that nothing else will be sent on that channel.
