Name three differences between REST and SOAP.

Protocol and Format: SOAP is a protocol that uses XML for message exchange and strictly defined standards (WS-*), whereas REST is an architectural style that typically uses HTTP and can work with various data formats (JSON, XML, HTML, etc.).

Complexity and Lightweight: SOAP is more heavyweight due to the need to process XML and complex standards, REST is simpler and lighter, making it more suitable for high-performance web services.

Stateless vs. Stateful: REST is stateless by default (no state preservation between requests), while SOAP can support both stateless and stateful interactions, which is important for some enterprise applications.
