Prelude This post will talk about why I’ve decided to make a new typed ML language based on the TypeScript ecosystem. It’s very opinion based, so you might not agree with all I write, but that’s okay. The language is not ready for general use yet, it has several bugs, but I thought I’d share some of my motivation. Writing it down and making it public also gives myself a good reason to keep working on it.

TLDR: Noah is a core contributor to Elm and provides some valuable perspective. He mentions some of the following topics for inspiring the development:

  • TypeScript has a great ecosystem. I think this means that the tooling will help speed up development.
  • TypeScript is missing function-based pure view functions (vs classes or functions with localized states).
  • TypeScript does not provide the Elm architecture (Model-View-Update).
  • Working with existing codebases with Elm is complicated.
  • Writing backend code with Elm is complicated.
