it�s good that

writing a node js app, op

javascript is awful regardless of how you write it, so I was looking up ways to write it in some less awful way and came across lodash-FP, which seemed to me to be pretty cool and good, so I used that, and it was pretty cool and good as far as javascript goes, so now I'm a currying liker

it�s good that you like fp in JavaScript because it�s not like it has integers

fp is cool until something doesn't quite work as you expect and you're left wondering wtf and you can't debug because your 'clever' and 'elegant' one-liner is actually wrapping 10 different things and all you can do is stare at it and think and hope some epiphany about what's wrong pops into your head.

The epiphany that should come to you is that all programming is garbage and you're wasting your life

*morpheus voice* what if i told u that if you use functional programming you won't have to debug (because you won't make bugs)

yeah but in the Linux �worse is better� way. if there are libs that handle your problem domain well then use it. if not then you�re on your own and do it yourself. it can be significantly easier to reason about with the caveat of an upfront cost of time, to formulate a solution and to understand anything. you could use fp features in otherwise OO langs I guess

spending time doing fp in erlang made me better at ruby which is extremely oo

list(filter(lambda x: x in big_butts, map(fart, butts))) feels fun to write even if it is less clear than a loop.

that's really hard to read, you want:

code:

map(fart, butts)
|> filter(lambda x: x in big_butts)
|> list()

Programming in a functional style can also be accomplished in languages that are not specifically designed for functional programming. For example, the imperative Perl programming language has been the subject of a book describing how to apply functional programming concepts.[29] This is also true of the PHP programming language.[30]

step 1 to functional php is using the "render mathy" tool `rm` on all your php files

my dude functional programming has been around as long as C has had function pointers

functional programming predates c by almost 20 years

Is this true of all fp? Like I've mainly done programming in the small type stuff for course work in scheme, sml, and some racket so I haven't had to deal with this, but it sounds hosed up.

e: Possibly less hosed up than having to worry about link order with large C projects though, now that I think about it.

nah

erlang & elixir are 100% fine with functions in a module being out of order (otherwise you can't have functions that call each other)

ruby's fine with cross-file dependencies as long as the names can be resolved at runtime

rust is good

i think you can be out of order in haskell, too. and also in elm and purescript

most haskellers are out of order in some way
