Reduced JavaScript

No magic: explicit, composable, idiomatic.
Works everywhere: modern web browsers and Node.

Reduce the language to its minimalist subset ✂️
Focus on readability and correctness first (pure functions, immutability, etc), on runtime performance second 🐢
Make tests simple and super fast ⚡
Avoid experimental features and third-party dependencies 🙅
