Avoid goroutine mistakes like data races and leaks by using channels, mutexes, and WaitGroups to manage concurrency safely.
Common goroutine mistakes include data races, goroutine leaks, and improper synchronization, which you can avoid by using channels, mutexes, and sync.WaitGroup to coordinate execution. Use the race detector to find data races and ensure every goroutine has a clear exit condition to prevent leaks.
var wg sync.WaitGroup
wg.Add(1)
go func() {
defer wg.Done()
// do work
}()
wg.Wait()
Goroutines are lightweight threads that run code concurrently, but they can cause crashes if they access shared data at the same time or never finish running. Think of them as workers in a factory who need clear instructions on when to stop and rules for sharing tools to avoid accidents. You use synchronization tools to ensure they work together safely without stepping on each other's toes.
