What does the principle of "complete" API mean?

• A. It has no extraneous features
• B. It covers all expected functionality
• C. It requires user feedback
• D. It limits method calls

Answer: (B)

The principle of a "complete" API refers to its ability to cover all expected functionality that users might need to successfully interact with the system. This means that a complete API provides all necessary endpoints, methods, and data structures to allow users to perform all desired operations without encountering gaps or missing features. For an API to be deemed complete, it should meet the needs of its intended user base, ensuring that it encompasses a wide range of operations that developers might want to perform. This is crucial because users rely on the API to accomplish specific tasks, and any missing functionality can lead to frustrations and increased development time. While extraneous features can detract from usability, and user feedback can help improve the API, these aspects do not define completeness. Limiting method calls pertains more to performance and efficiency rather than the completeness of the API's functionality. Thus, the focus on covering all expected functionality is what makes the principle of "complete" significant in the context of API design.
