## Notes

Bun is a JavaScript and TypeScript runtime written in Rust, shipped as one executable that also contains a package manager, a test runner and a bundler. The runtime is described as a drop-in replacement for Node.js, and the bundler is started with the `bun build` command or the `Bun.build()` API. It is installed with a shell script, npm, Homebrew or a Docker image. The project's homepage states that Bun has joined Anthropic, and the code is maintained in the oven-sh GitHub organization.

## Worth knowing

The LICENSE file describes Bun itself as MIT-licensed and states that Bun statically links JavaScriptCore and WebKit, which it lists under LGPL-2. The file quotes the LGPL-2 wording that covers statically linked libraries.
