Your question is Maintainable, Well-Documented Code. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you ensure your code is maintainable and well-documented for the rest of your team? Explain the practical habits you use during implementation, code review, testing, and handoff. Include how you decide what belongs in code comments, API documentation, tests, or architectural notes.
