Mutexes in Go

 Mutexes in Go

Mutexes are a synchronization mechanism provided by the sync package. A Mutex can be used to provide exclusive access to a shared resource.

Here's an example of using a Mutex:

var mu sync.Mutex

var counter int

func increment() {

    mu.Lock()

    counter++

    mu.Unlock()

}

for i := 0; i < 10; i++ {

    go increment()

}

time.Sleep(time.Second)

fmt.Println(counter) // prints 10

In this example, we create a Mutex and a shared counter variable. We then create 10 goroutines that call the increment function, which increments the counter using the Lock and Unlock methods of the Mutex.

The Mutex ensures that only one goroutine can access the shared resource at a time, preventing data races and ensuring consistency.
