Learning Functional Programming in Go

Haskell version of compose

We'll cover the Haskell version of composing Humanize and Emphasize:

humanize b = if b then "yes" else "no"emphasize str = str ++ "!"compose g f = \x -> g (f x)emphasizeHumanize = compose emphasize humanizeemphasizeHumanize True

That's it!  Those five lines are equivalent to the 25 lines of Go code!

I am not at all advocating for any Gophers to switch to Haskell--there are far too many reasons to keep coding and deploying Go solutions to address here. I include the Haskell code for informational purposes. As mentioned earlier in the book, category theory trickles down from the brains of the mathematicians directly into Haskell. So, if we want to be good, pure functional programming Gophers, then we should learn ...
