Always have x number of goroutines running at any time

Question

I see lots of tutorials and examples on how to make Go wait for x number of goroutines to finish, but what I\'m trying to do is have ensure there are always x number running

Answer 1

1. Create channel for passing data to goroutines.
2. Start 20 goroutines that processes the data from channel in a loop.
3. Send the data to the channel instead of starting a new goroutine.
