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?
I mostly work in Go, but I helped maintain one project written in Elixir for a while. It was rather interesting. It’s certainly a different way of thinking. It does reduce the risk of certain side effects but, as with everything, it has its own downsides.
