Elm is a functional programming language inspired by ML and Haskell. It compiles to HTML, CSS, and JavaScript, allowing developers to build web applications in a functional style. Elm uses immutable values and static typing to prevent runtime exceptions. The Elm architecture defines a common pattern for building Elm applications with a model, view, and update function to manage data flow in a declarative way.
