Does the Map class ensure safety when used in a multithreaded environment?

In Go, the standard Map type is not safe for concurrent use without additional synchronization. If multiple goroutines read and write to a Map simultaneously without protection, it can lead to data races and panics.

To ensure safety during concurrent access, you can use:

• Mutexes (sync.Mutex or sync.RWMutex) to lock access to the Map.
• Specialized structures, such as sync.Map, which are designed with concurrent access in mind.

Example of using sync.Map:

var m sync.Map
m.Store("key", "value")
value, ok := m.Load("key")
if ok {
    fmt.Println(value)
}

Thus, the classic Map does not guarantee safety in multithreading, but there are tools for safe working with associative collections.
