> How can people rationalize this I've personally learnt a lot from Leetcode, and found the process really valuable. I learnt a ton from bashing my head against the wall until dynamic programming made sense. I anecdotally code much, much faster, in all languages, having done it. It's like doing college homework again. Something useful that makes you a better "coder," (not necessarily a better engineer). It was a damn hard slog, but having done the hard slog I really enjoy having done it. I'm not going to pretend it's not time consuming or I'd be happy doing it if I was a busy parent. But in hindsight I've really enjoyed having done it, and found it extremely valuable. I suppose it's for people who just have that kind of time/energy/enthusiasm for programming/their career.
