Haha, someone was blaming 'typescript' after they'd made this exact mistake in Ask HN : https://news.ycombinator.com/item?id=26039826 https://news.ycombinator.

Strange coincidence.
Edit: I always wondered if jquery's .each deliberately had a signature of function(i, ele) to discourage people from mistakes like this, or if it was a happy accident.
- brailsafe 6y agoYou could derive a decent interview question out of that. Not the specific output of the bad call to parseInt, but simply "What arguments can you pass into parseInt?", and then simply ask about why it would be bad to pass as a callback to map. I'd probably have tripped up on the latter having not read this post, because I'd have never thought to not explicitly pass the radix to parseInt and rarely use anything but anonymous functions in a map call. Though on second thought, maybe not a great question, hard to say. I know I've tripped up on the std sort function having not had used it in a while.
