Elm

简介

Elm: Functional Frontend

Elm is a functional language that compiles to JavaScript.

功能

Elm 架构核心的三个概念：

• Model — the state of your application
• View — a way to turn your state into HTML
• Update — a way to update your state based on messages

Elm is also very fast and very small when compared with React, Angular, Ember, etc.
