Not disputing the code quality of either above project, but over valuing brevity / being concise is a common cause of problems. Specifically, people will often sacrifice readability and robustness for brevity.

At this point in my career I don't really value being concise at all. Which is not to say you shouldn't ever think about "Can I write less code here?" but the goal there should be writing less code to make what you're writing more robust, more stable, more readable and not just shorter.

If there's one thing I could tell every programmer early in their career (including a younger me) it would be; nobody's going to be impressed with how clever you were when they're frustrated trying to understand what the heck is going on. Including you in 6 months.
