Once upon a time, there was a programmer named Jarred Sumner who loved to code in JavaScript. He spent most of his time creating unique web applications using the language. However, he faced a major challenge - the runtime speed of JavaScript.

At that time, the two most popular JavaScript runtimes were Node.js and Deno.js.
Though they were great, they weren't fast enough for Jarred Sumner's liking. He dreamed of a new runtime that could handle heavy workloads with ease and speed.

One day, Jarred Sumner stumbled upon a new runtime called Bun.js. He was intrigued by its claims of being the fastest JavaScript runtime out there. He decided to give it a try and was blown away by its performance. With Bun.js, Jarred Sumner was able to create complex applications at lightning speed. He could handle more requests and process data faster than ever before. He became the talk of the town, with everyone curious about his secret weapon. Soon, more and more developers started using Bun.js and its popularity grew rapidly. It became the new buzzword in the JavaScript community, with people raving about its speed and efficiency.

Who the Hell is Bun.js?

Node.js and Deno, there's a new kid on the block - Bun! This JavaScript/TypeScript runtime is causing a stir in the developer community with its lightning-fast performance, quick start-up time, and all-in-one toolset.

Bun is not just another runtime, it's a complete package! This contemporary runtime comes with a bundler, transpiler, and package manager, making it the ultimate tool for web development. And that's not all - the NPM client included in Bun uses the Node module resolution technique, making it easy to transition from Node to Bun.

But wait, there's more! Bun has grand aspirations. Its goal is to take on the world's JavaScript outside of browsers, tackling complex infrastructure and improving performance like never before.

It's like a sports car of the JavaScript runtime world, starting and performing lightning-fast compared to other engines like V8.

And get this - the whole thing is written in Rust, a low-level programming language that's like the Batman of programming languages with its sleek, efficient performance and manual memory management skills.

But that's not even the coolest part. Most of Bun is written from ZIG, including its own JSX/TypeScript transpiler, npm client, bundler, SQLite client, HTTP client, WebSocket client, and more. It's like a superhero team of tools, all working together to create the ultimate runtime experience.

Getting started

---

To install Bun, run this install script in your terminal. It downloads Bun from GitHub.

curl -fsSL https://bun.sh/install | bash

// http.js
export default {
  port: 3000,
  fetch(request) {
    return new Response("Welcome to Bun!");
  },
};

Run it with Bun:

bun run http.js

Then open http://localhost:3000 in your browser.

See more examples and check out the docs. If you have any questions or want help, join Bun's Discord.

Thank You
