How does MessagePack reduce data size compared to other serialization formats?

MessagePack reduces data size through a binary format that encodes data more compactly compared to text formats like JSON or XML. Instead of storing data as strings, MessagePack uses efficient data types and minimal bytes to represent numbers, strings, arrays, and objects. For example, integers can occupy from 1 to several bytes depending on their value, and keys and strings are encoded without unnecessary characters and spaces. This significantly decreases the size of serialized data and speeds up its transmission and processing.
