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.

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.

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 am drawn to Elm because it is a safe, reliable, and refactorable alternative to building webapps. It's an approachable language that not only supports the dynamic nature of greenfield projects, but it can also be adopted in small steps within legacy apps implemented in other front-end solutions.

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.

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 worked with Elm professionaly and I love it! Trusting the language is such a relief on your mind, as a developer you can really start to express yourself and let the code flow, the compiler will watch your back!
Fun. Challenging. Interesting
