Using a debugger is basically out of the question. The theory is that the conciseness and lack of fluff makes it easier to reason about once you’ve mustered the requisite focus.
Not all array languages fold right. K's reduce is a left fold and BQN has a mix of both. My understanding is that a right fold was chosen because it's more expressive. You get alternating sums when folding subtraction with a right fold and something less interesting if you use a left fold. FWIW, that(s my understanding of the history. I don't actually think the argument is very compelling.
In my professional experience most code never gets read by anyone other than the original author and when it is read it's often reluctantly. If you have any links to studies which show that code is read more often than it is written, I'd be interested to read them.
I, just, can't believe you could think that. Have you never debugged code you didn't write? There are six billion people in the planet and you think it's more likely that a given piece of professional code will only ever be read by one person? A person leaves the company and you just delete everything they wrote so nobody can read it?
I'm guessing this means you don't have any studies to back your claim. Neither do I, but in my experience most code is left to run when someone leaves the company. If issues come up, someone is assigned to support the code and nine times out of ten (okay, maybe eight) the person on support decides to rewrite the code. FWIW, the six billion people stat hardly seems relevant, right?
So you have a study? Because I’ve seen way more people who think readability in code is paramount, and I don’t think I’ve ever seen the take that it’s usually never read again.
I think I speak for everybody when I say that if a language isn't immediately intelligible to me within two seconds of barely glancing at it then it isn't worth anyone's time. Programmers are lazy. That's not a criticism. It's something to aspire to. [end sarcasm]
