Bun is a modern JavaScript runtime like Node or Deno. It was built from scratch to focus on three main things:
Extremely lightweight (it has the edge in mind).
New levels of performance (extending JavaScriptCore, the engine).
Being a great and complete tool (bundler, transpiler, package manager).

node_modules bun implements Node.js' module resolution algorithm, so you can use npm packages in bun.js. ESM and CommonJS are supported, but Bun internally uses ESM.
In bun.js, every file is transpiled. TypeScript & JSX just work.
bun supports "paths", "jsxImportSource"and more from tsconfig.json files
Bun.Transpiler bun's JSX & TypeScript transpiler is available as an API in Bun.js
use the fastest system calls available with Bun.write to write, copy, pipe, send and clone files.
bun.js automatically loads environment variables from .env files. No more require("dotenv").load()
bun ships with a fast SQLite3 client builtin bun:sqlite
Node-API bun.js implements most of Node.jÀ' native addons API, Node-API (NAPI). Many Node.js native modules just work.
bun:ffi call native code from JavaScript with bun's low-overhead foreign function interface
node:fsnode:path bun.js natively supports a growing list of Node.js core modules along with globals like Buffer and process.
How does Bun work?
Bun.js uses the JavaScriptCore engine, which tends to start and perform a little faster than more traditional choices like V8. Bun is written in
