At work, a common mistake I notice when reviewing candidates’ home assignments is how they wire goroutines to channels and then return early. The pattern usually looks like this: start a few goroutines each goroutine sends a result to its own unbuffered channel in the main...
Prevent goroutine leaks caused by early returns with unbuffered channels. Learn buffering, draining, errgroup patterns, and goleak testing.
