          <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's JavaScript outside of
            browsers, bringing performance and complexity enhancements to your
            future infrastructure, as well as developer productivity through
            better, simpler tooling.

            </a>{" "}
            and perform a little faster than more traditional choices like V8.
            Bun is written in{" "}
            <a href="https://ziglang.org/">
              <Zig></Zig>
            </a>
            , a low-level programming language with manual memory management.
            <br />
            <br />
            Most of Bun is written from scratch including the JSX/TypeScript
            transpiler, npm client, bundler, SQLite client, HTTP client,
            WebSocket client and more.
          </p>
          <h2>Why is Bun fast?</h2>
          <p>
            An enormous amount of time spent profiling, benchmarking and
            optimizing things. The answer is different for every part of Bun,
            but one general theme:{" "}
            <a href="https://ziglang.org/">
              <Zig></Zig>
            </a>
            's low-level control over memory and lack of hidden control flow
            makes it much simpler to write fast software.{" "}
