Not in Haskell and other pure languages. Pure functional programming is used to construct larger programs from smaller ones, which only when finally executed by the runtime produce output.
- rwjwjuwjudf 11y agoAre there any programs that produce output before they are executed?
- willtim 11y agoIt is not easy describing pure functional programming in two sentences. I encourage you to read up on it yourself. Again, IO is not a side-effect in pure languages such as Haskell. And again, the absence of side-effects best defines functional programming, not any particular feature, which imperative languages can and do steal.
