Summary
Goroutines 101: A basic walkthrough explains Go's concurrency model, focusing on how the go keyword starts goroutines, why main may exit before goroutines run, and how to synchronize using WaitGroup. It covers the OS-thread versus goroutine model, the m:n scheduler, and how GOMAXPROCS controls parallelism, with practical code examples illustrating starting goroutines and coordinating their completion.
