Bun 리뷰

Node.js is the most mature and widely adopted JavaScript runtime, boasting a massive ecosystem of packages and a battle-tested reputation for stability and reliability.

Unlike Bun's all-in-one approach, Node.js provides the runtime and relies on separate community-driven tools (like npm for package management, Webpack/Vite for bundling, and Jest for testing). While Bun often outperforms Node.js in raw speed for startup, package installation, and certain workloads, Node.js offers unparalleled ecosystem depth and flexibility for complex, customized build pipelines.

Deno is a modern JavaScript, TypeScript, and WebAssembly runtime that prioritizes security by default, web standards alignment, and includes a complete built-in toolchain.

Similar to Bun, Deno offers an integrated developer experience with native TypeScript support and built-in tools, but its core philosophy emphasizes security through explicit permissions and web standards. While Bun focuses on raw performance and Node.js compatibility, Deno provides a more secure-by-default environment and a strong alignment with browser APIs, often showing competitive performance but generally being slightly slower than Bun in raw speed benchmarks.

Vite is a blazing-fast frontend build tool and local development server that leverages native ES modules for instant server starts and lightning-fast Hot Module Replacement (HMR).

Vite is primarily a build tool for frontend development, whereas Bun is a full JavaScript runtime that *includes* a bundler. While Bun's integrated bundler can be very fast, Vite's extensive plugin ecosystem and optimized production builds (using Rollup) often make it the preferred choice for complex frontend projects, and it can be used effectively *with* Bun as the runtime.
