In Go, maps are used to store key-value pairs, but the standard map type is not thread-safe. To handle concurrent access, Go provides the sync.Map type, which allows for safe access to shared data. The sync.Map type is optimized for concurrent read and write access, making it a good choice for high-concurrency applications. However, there are some differences between sync.Map and map in Go that developers should be aware of. This article explores the differences between these two types of maps and helps developers determine which one is the best choice for their specific use case.
