The F# syntax is an incredibly simple bit of syntactic sugar.
Just replace this:
x |> f
With this:
f(x)
For the join example, you must do this:
xs
|> (x => x.join(' '))
It de-sugars to:
(x => x.join(' '))(xs)
... which of course is simply:
xs.join(' ')
- captainmuon 4y agoSure, I know. What I actually mean is that I don't grok curried functions. Does join(a)(b) mean join(a, b) or join(b, a)? Does it mean a.join(b) or b.join(a)? And is a or b the delimiter? I don't really feel confident without looking it up or trying it out. I have a similar problem with Haskell's function syntax a -> a -> a. If the function was called makeJoinerBy(sep)(array), it would be somewhat clearer: join = makeJoinerBy(' ') result = join(array)
