A worker may need to wait until a queue contains an item. A producer may need to wait until that queue has free capacity. Several goroutines may need to sleep until a service becomes ready.</p> <p>Polling the state in a loop wastes CPU or forces you to invent arbitrary sleep intervals. Channels solve many coordination problems more directly, but they are not always a natural fit when several goroutines already share state protected by a mutex and need to wait for <strong>predicates</strong> over that state.</p>
