The article provides examples of how using as const and strict type definitions can help ensure the correct result is returned. The author argues that while avoiding return types may seem simpler, it can lead to lies and inaccuracies in the overall type system. The article emphasizes the importance of accurately representing the true type of a functions result in order to prevent errors and improve code quality.
