What is the suggested course of action when in doubt about functionality in an API?

• A. Leave it out or mark it internal
• B. Implement it anyway
• C. Discuss it with other developers
• D. Test it with users first

Answer: (A)

Choosing to leave out or mark functionality as internal is a prudent approach when there is uncertainty about its purpose or necessity within an API. This method helps maintain the API's clarity and integrity, ensuring that developers using it aren’t exposed to potentially confusing or incomplete features. By opting to exclude uncertain functionality or label it as internal, you prioritize stability and usability over the risk of introducing poorly understood elements that could lead to confusion or misuse. This approach stresses the importance of transparency in design: if a feature is not well-defined or understood, it is often more beneficial to avoid exposing it to end-users. It encourages careful consideration and deliberation before any public exposure of API functionalities, thereby supporting a cleaner and more maintainable API surface area. Engaging in discussions with other developers or testing features with users could provide valuable insights, but the priority should always be on ensuring what is already available is robust and well-documented first. Adding functionality without clarity could lead to complications that compromise the API’s reliability.
