  "account": "The sync.Map data structure in Go offers concurrent versions of common map operations, allowing multiple goroutines to safely call Load, Store, and Delete without the need for external locking. This makes it a more lightweight alternative to using a plain map with a mutex. However, sync.Map does not provide a Len method, and iterating over the map using range does not guarantee a stable order, as the current implementation may choose random starting offsets for every range loop.",
