<h1>How it works</h1>
<p>
Bun.js uses the{" "}
<a href="https://github.com/WebKit/WebKit/tree/main/Source/JavaScriptCore">
JavaScriptCore
</a>{" "}
engine, which tends{" "}
<a
target="blank"
href="https://twitter.com/jarredsumner/status/1499225725492076544"
>
to start
</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>
<h1>Why is Bun fast?</h1>
<p>
An enourmous 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.{" "}
