Milliseid ülesandeid lahendab sync pakett Go programmeerimiskeeles?

The sync package in Go provides synchronization primitives for managing concurrent access to resources and coordinating goroutines.

Main tasks solved by the sync package:

• Mutex (Mutex) — to protect critical sections and prevent simultaneous access to shared data.
• RWMutex — a mutex with separation for reading and writing, allowing multiple goroutines to read data simultaneously but blocking writing.
• WaitGroup — to wait for a group of goroutines to finish.
• Once — to perform initialization only once.

Example of using Mutex:

var mu sync.Mutex
var counter int

func increment() {
    mu.Lock()
    defer mu.Unlock()
    counter++
}

Thus, the sync package helps to work safely with concurrency and avoid race conditions.
