I hear they are good, make it easier to maintain code-bases. Most often I reach for python to get the job done. Does anyone have experiences with functional languages for larger projects?
In particular I am interested to learn more on how to handle databases, and writing to them and what patterns they come up with. Is a database handle you can write to not … basically mutable state, the arch-nemesis of functional languages?
Are functional languages only useful with an imperative shell?
they can do some clever stuff with composition but have never really caught on because they become hard to reason about very quickly
as someone else mentioned, imperative languages have promoted the useful functional stuff so that it’s in common usage
