Bun

Bun is a high-performance JavaScript runtime designed as a modern alternative to Node.js, integrating essential development tools such as a bundler, transpiler, test runner, and package manager into a single executable. It is built from scratch using Zig and JavaScriptCore to achieve faster startup times, reduced memory usage, and aims for full compatibility with the Node.js ecosystem, supporting JavaScript, TypeScript, and JSX out-of-the-box.
