elm

Elm is a domain-specific programming language for declaratively creating web browser-based graphical user interfaces. Elm is purely functional, and is developed with emphasis on usability, performance, and robustness. It advertises "no runtime exceptions in practice",^[6] made possible by the Elm compiler's static type checking.

After several years with Elm in production, I can full heartedly say that Elm's tagline "A delightful language for reliable webapps", is correct.

Elm is a language that compiles to JS, and has no run time exceptions.

It's like Vue, React or Angular2, only completely different.

If you are an avid user of the aforementioned libraries, this session is for you.
