Hi there again!

I’m working on a project “Boss Machine” now. The instruction offers us to write such route: DELETE /api/ideas/:ideaId to delete a single idea by id. I did it and it passed the test properly. But there is no deleting idea functionality in the application. Even video doesn’t demonstrate this functionality. Do we write this route only for test sake?
