Bun JavaScript Runtime

Bun is a modern, all-in-one JavaScript runtime designed for speed and simplicity, positioning itself as a direct and faster alternative to Node.js. Built from the ground up using the Zig programming language and powered by Apple's JavaScriptCore engine, Bun integrates essential development tools that typically require separate configurations, including a package manager, test runner, and bundler. This integrated approach, combined with its focus on performance, aims to significantly reduce project complexity and accelerate development workflows by providing a cohesive, out-of-the-box experience with native support for modern features like TypeScript and JSX.
