Getting started with Bun and React

Bun is a new JavaScript runtime that is gaining attention for its speed and efficiency, positioning itself as a strong competitor to established runtimes like Node.js and Deno. Developed by Jared Sumner and released in 2021, Bun is an all-in-one solution that includes a native bundler, transpiler, task runner, and npm client, and it supports both JavaScript and TypeScript projects. Bun is designed to be faster than its counterparts due to its use of JavaScriptCore, the Zig programming language for API writing, and various optimizations, making it particularly effective for I/O-intensive operations. It is Node-compatible, supporting many Node.js modules and APIs, and includes features such as a CSS-in-JS tool, template builder, and environment variable loader. The runtime also enables quick React app creation with Vite, benefiting from Bun's speed, and offers a built-in test runner that is compatible with Jest. Although Bun is still in its early stages and may present integration challenges with some libraries, it is evolving rapidly, with ongoing updates addressing potential issues.
