Can I do FP in my language?

A very common question I get from experienced programmers is "What does an FP language give me that I don't already have? Can't I just do FP in m... [Read Full]

Elm is a good one to get your feet wet too (and develop HTML5 UIs in the process). Because all your Elm code is purely functional, refactoring is quite safe... make your changes and then fix all the compiler errors, and it probably just works. This reduces the penalty for early mistakes.


Elm is awesome for learning functional programming!


I really want an excuse to use Elm in a real-world context. Still haven't needed it, but still excited about the language.

It's good for applications, maybe less so for content-based websites. (Based on your preact post and concern with deployed size.) Give it a try for some internal tools and see what you think.

I've found that where the difficulty lies in Elm is backwards from most UI frameworks. Most of them are easy/moderate to get going, but become increasingly hard to maintain over time. Elm requires a little bit more effort to get started up front (adjusting to FP mainly), but maintenance difficulty doesn't increase much over time. Maintenance is still work, but not particularly risky work.

We use it production, both internal and customer-facing.


Having many different ways to solve a problem comes with great amount of expertise needed to pick the best one.
I need to try Clojure once more :) Thank you for the reading!


What a blog that would be! Maybe we could start a new social network where we answer yes or now questions. The UI to answer is just 2 radio buttons. ;)


Yes, programming paradigms are not the same as programming languages. I've been writing a lot about this lately over at
