+ <h2>Tell me more about Bun</h2>
+ <p>
+ Bun is a modern JavaScript runtime like Node or Deno. It was built from scratch to focus on three main things:
+ </p>
+ <ul>
+ <li>Start fast (it has the edge in mind).</li>
+ <li>New levels of performance (extending JavaScriptCore, the engine).</li>
+ <li>Being a great and complete tool (bundler, transpiler, package manager).</li>
+ </ul>
+ <p>
+ Bun is designed as a drop-in replacement for your current JavaScript &amp; TypeScript apps or scripts — on
+ your local computer, server or on the edge. Bun natively implements hundreds of Node.js and Web APIs,
+ including ~90% of<!-- -->
+ <a href="https://nodejs.org/api/n-api.html" target="_blank">Node-API</a>
+ <!-- -->functions (native modules), fs, path, Buffer and more.
+ </p>
+ <p>
+ The goal of Bun is to run most of the world&#x27;s JavaScript outside of browsers, bringing performance and
+ complexity enhancements to your future infrastructure, as well as developer productivity through better,
+ simpler tooling.
+ </p>
+ <h2>Batteries included</h2>
