I guess you could call this an OOPsie
We have been played for absolute fools
Repeat after me:
public static void main(String[] args)functional programming ftw

Functional Programming Practice: Quicksort
Been working in Clojure for over a decade now, and would never never go back to using imperative/OOP at this point.
TBH Rust is pretty nice, it borrows (pun intended) a lot of ideas from the functional world (algebraic data types, traits, closures, affine types to an extent, composition over inheritance, and the general vibe of type-driven development), but it’s much easier to write fast, efficient code, integrate with decades of libraries in imperative languages, and the ecosystem somehow feels mature already.
I’m just a hobbyist but…are you guys using exceptions like they’re conditional statements?? I thought those were for only when shit is seriously wrong and execution can’t continue in the current state. Like if some resource was in a bad state or some input was malformed.
Or maybe I haven’t worked on anything complex enough, I dunno.
I suppose it depends on the language? For the most part I think you’re right. Exceptions are only used (if at all) in situations where a program diverges unexpectedly from its normal flow. But take a language like Python. They’re just everywhere. Even your plain old
forloop ends on an exception, and that’s just business as usual.Python programmers appear to actively promote the ‘easier to ask forgiveness, than permission’ style nowadays. This article has a measured take: https://realpython.com/python-lbyl-vs-eafp/
