About Elm

module HelloWorld exposing (helloWorld)


helloWorld : Maybe String -> String
helloWorld name =
    case name of
        Just name_ ->
            "Hello, " ++ name_ ++ "!"

        Nothing ->
            "Hello, World!"

Elm is a pure, functional language that compiles to javascript.

It was designed by Evan Czaplicki as part of writing his thesis on Concurrent FRP for Functional GUIs and evolved into a language to help make making user interfaces better.

Elm's goal is to be the simplest and best language for making web-based user interfaces.

Elm aims to completely eliminate runtime exceptions by combining an aggressively helpful compiler with solid architectural principles.

You can learn more about Elm at the official website.

Exercism is a great website

Exercism is a great website where I was able to have some very interesting challenges.

Relaxed. Encouraging. Supportive.

I like Elm for its friendliness: I'm more confident in my Elm code than I am in code in any other language, and I never feel pressured to use things I don't understand.

Elm was my introduction to typed languages and a gateway for me to functional programming. I was lucky enough to learn it on the job, and have since adopted it as my main frontend language.

I use Elm for all my personal projects where I need a frontend framework (instead of React for example). Elm's development is "slow" compared to other languages but this makes it even more appealing to me.

I use Elm for hobby projects and occasionally at work. I like it for a lot of technical reasons, but most of all for the great community.

I'm a software lead / architect / manager type thing and I have a strong focus on code quality. Elm is the first functional language I've learned and it's impressively easy. The language has a strong focus on simplicity and a single recommended way of doing things, which is a refreshing change in the Front End world. It sits very well in it's target niche, and the runtime essentially provides an impure abstract syntax tree interpreter, leaving all your code 100% pure / functional. There is a strong and vibrant community, which is both innovative and supportive to newcomers.

I love everything about Elm. My days are spent programming in Elm as a professional, my weekends are spent working on open source Elm projects and packages. I'm a member of the Elm core team and you can always find me on the Elm-lang Slack!
Fun. Challenging. Interesting
