I am a front-end developer and seeing this kind of nonsense really just makes me depressed. Never in my career have I ever had to manually implement any of these algorithms and the fact that front-end developers are expected to know these manually really highlights a problem in the hiring process. I am not academically minded, I am self-taught so maybe that has something to do with it. But I've been a developer for over ten years now and I am very good at my job, never been fired and always manage to get a job at any place I've worked at.
