Bun's superpowers

• Speed
  Bun processes start 4x faster than Node.js currently

  You can directly execute .jsx, .ts, and .tsx files. Bun's transpiler converts these to vanilla JavaScript before execution

Bun's superpowers

• ESM & CommonJS compatibility
   

import { stuff } from "./es-module.js";
import Stuff from "./es-module.js";
const myStuff = require("./my-commonjs.cjs");

Bun's superpowers

• Web-standard APIs
  Bun implements standard Web APIs like fetch, WebSocket, and ReadableStream. Leveraging JavaScriptCore engine, developed by Apple for Safari, so some APIs like Headers and URL directly use Safari's implementation.
   
• Node.js compatibility. In addition to supporting Node-style module resolution, Bun aims for full compatibility with built-in Node.js globals (process, Buffer) and modules (path, fs, http, etc.)
  This is an ongoing effort that is not complete

Bun's so faaast...
