Which synchronization tools from the list have you used in your project?

In my Go projects, I used the following synchronization tools:

• Mutex (sync.Mutex) — for protecting critical sections and preventing concurrent access to shared data.

• RWMutex (sync.RWMutex) — when I need to allow multiple goroutines to read data simultaneously but block writing.

• WaitGroup (sync.WaitGroup) — to wait for a group of goroutines to finish.

• Channels — for data transfer and synchronization between goroutines, often preferred over mutexes in Go.

For example, to safely update a shared counter, I used sync.Mutex:

var mu sync.Mutex
var counter int

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

Using these tools helps avoid data races and ensures correct operation of concurrent programs.
