How can data races that occur during concurrent access to resources in a multithreaded environment be eliminated?

Answer from AI

To eliminate data races in a multi-threaded environment in Go, several approaches can be used:

  1. Mutexes (sync.Mutex) — block access to shared resources, allowing only one goroutine to work with it at a time.

  2. Channels — enable safe data exchange between goroutines, avoiding direct access to shared variables.

  3. sync/atomic package — provides atomic operations for primitive types, helping to avoid races during simple operations.

Example with a mutex:

import (
    "sync"
)

var mu sync.Mutex
var counter int

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

Using channels:

ch := make(chan int)

func worker() {
    for val := range ch {
        // process val
    }
}

func main() {
    go worker()
    ch <- 42
    close(ch)
}

The choice of method depends on the specific task and program structure.
