Go's goroutines and channels enable a set of well-established concurrency patterns that solve common problems — distributing work, fanning out/in, pipelines, and rate limiting. Knowing these idiomatic patterns lets you build correct, efficient concurrent systems.

wg sync.WaitGroup

wg.Add()
{
wg.Done()
job := jobs {
results <- process(job)
}
}()
