The answer
Use a mock API when learning a specific frontend concept, because stable data isolates the skill. Use a real API when you want to practice messy integration like auth, errors, and rate limits. Both have a place at different stages.

Mock APIs give realistic, stable, predictable data without authentication, rate limits, or backend setup. They let you focus on frontend skills like routing, state, and data fetching without external surprises.
Real APIs teach you to handle authentication, rate limits, changing data, CORS, and unexpected response shapes. They expose you to the failure modes and messiness of production integration that mocks rarely show.
Because mocks rarely fail, which can make you lazy about error handling. Force yourself to handle loading, error, and empty states even with mocks, so the habit transfers when you move to real APIs.
