You and me seem to have pretty different definitions of "unclean" .... you might want to take a look at currying ... and "unclean" libraries such as ramda 😅
Guess what isQueenOfSpades contains in ramda docs? Guessing not works in here, in such way need to read source to know. While in normal JS where naming matters it is a boolean.
Is it clean? In common programming sense, name is given to describe what function or variable does, so in this way no, it's not clean. Functional programming has roots in math where naming doesn't matter, they are cool with formulas like this one, but it's not right to expect your teammates will be happy of guessing how your log works.
You don't need to read the source to understand a function, nowadays we have inline docs and typing systems.
Is it really hard for you to figure out what isQueenOfSpades does? Do you prefer the name to be isAnObjectWhichContainsARankQAndASuitOfSpades instead?
A name should hint what a function does, but you don't need to explain the entire implementation in the name.
If you're working with currying, you already know every function is an unary that returns a new function until you have all the arguments.
Programming has roots in binary and asm, and that doesn't have anything to do with the way we do things nowadays. I would never advocate for naming practices like the ones used in languages like Haskell, with single letters. Using Haskell to debate FP practices is like using ASM to justify that programming is hard to understand.
Nobody needs to "guess" how something works if it has good docs, types and a clear enough name.
Do you use libraries without knowing what the utils they provide will return, and relying only on the name? I imagine back in the day you had a really hard time with jQuery's $.get if that's the case. My teammates are perfectly fine with a log function, because when they use it they get autocompletion in their editors telling them the arguments that function takes, the thing it returns, and if they use it wrong they get a red squiggly underline to let them know, not to mention that if they hover over the function or the arguments, they get examples from the JSDocs 😄
Agree, makes sense now, I get used to rely on naming and I'm not hovering things at all, while in this practice programmer has to rely on hovering hint. I've tested and it works nicely, even in plain JS I got hint
log = (prepend: any) => (log: any) => void
Libraries is a different thing and only way is it read docs and memoize frequently used stuff.
$.get - jQuery was intended to do what document.querySelector does before it appeared, so I expect it to get element by selector. I honestly didn't check docs. But if it was ramda I would expect: get(key, object) and get(key)(object), but wrong, it's a 'prop' in ramda.

So in general thanks for response, in editors it's not hard to get hints.
But not everywhere, while reviewing code in github it can give you hints as well, but far less intelligent and it won't work so nicely.
2 and 3 isAnObjectWhichContainsARankQAndASuitOfSpades
I would have a type Card = { rank: string, suite: string }
And a function getIsCardAQueenOfSpaces.
And now I can assign it to local variable isQueenOfSpaces and use it in imperative way
4 Makes sense, but it means whole project need to follow FP and currying to stay predictable, everyone in team must be good with FP and be on same page
Do you use libraries without knowing what the utils they provide will return, and relying only on the name?
Yes, sure, other teammates may introduce libs which I never used and I'm reviewing the code, and usually it's understandable just by looking on name and usage

We're a place where coders share, stay up-to-date and grow their careers.
