A practical experiment using vanilla JavaScript, Web APIs, and Proxy-based state to create reactive, declarative UI without frameworks.

Key Highlights

  • January, 12th 2026 5 min read Modern UI frameworks offer abstraction layers that make user interfaces declarative and reactive.
  • However, the web platform itself exposes primitives that can be compos… JAX in pure JavaScript, as a flexible machine learning library and compiler.
  • Im excited to release jax-js, a machine learning library for the web.
  • You can think of it as a reimplementation of Google DeepMinds JAX framework (similar to PyTorch) in pure JavaScript.
