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.

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!

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

Elm is a great language for folks to learn functional programming. Elm was the first functional programming language I've learned, and is great for teaching fundamental concepts and paradigms used when creating single-page web applications!

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.
Fun. Challenging. Interesting
