Bun. “Bun is a fast all-in-one JavaScript runtime”—this is very interesting. It’s the first project I’ve seen written using the Zig language, which I see as somewhat equivalent to Rust. Bun provides a full Node.js-style JavaScript environment plus a host of packaged tools—an npm install client, a TypeScript transpiler, bundling tools—all wrapped up in a single binary. The JavaScript engine itself extends JavaScriptCore. Bun also ships with its own wrapper for SQLite.
