🚀 Key Advantages of Bun

1. Blazing Fast Performance

Faster execution: Bun is written in Zig and optimized for speed, often outperforming Node.js and Deno.
Quick startup: Apps launch faster due to lower overhead.
Efficient dependency resolution: Installs packages 20x–100x faster than npm/yarn/pnpm.

2. All-in-One Toolkit

Bun replaces multiple tools with built-in features:

Package manager: bun install (no need for npm/yarn/pnpm).
Test runner: bun test (Jest-compatible, no extra setup).
Bundler: bun build (like esbuild or Webpack).
