What methods prevent deadlocks when working with multithreading?

Answer from AI
In Go, several approaches are used to prevent deadlocks when working with multithreading:
- Avoid cyclic dependencies: always acquire mutexes in the same order.
- Use channels: they allow safe data exchange between goroutines without explicit locking.
- Use timeouts and contexts: with
context.Context, operations can be canceled to avoid infinite waiting. - Minimize lock holding time: keep the mutex locked only for a short critical section.
Example of using channels for synchronization:
ch := make(chan int)
go func() {
ch <- 1 // send value
}()
val := <-ch // receive value
fmt.Println(val)
This approach helps avoid mutex-related deadlocks.
