Bun, an all-in-one toolkit for building, testing, debugging, and running JavaScript and TypeScript apps, has reached stable production-ready status as of September 8.
Positioned as a drop-in replacement for Node.js, Bun is a single executable intended to eliminate complexity and slowness without tossing away everything that is “great” about JavaScript, Bun’s developers said. They bill Bun as a fast JavaScript runtime that simplifies JavaScript development by eliminating the “layers and layers of tooling that have accumulated on top of each other.”
