Otherwise wildly different results for different JavaScript runtimes

const url =

console.log(navigator.userAgent);

if (navigator.userAgent.includes("Bun")) {
  try {
    const text = await (await fetch(url)).text();
    const dataURL = `data:text/javascript;base64,${btoa(text)}`;
    const { Buffer } = await import(dataURL);
    console.log(Buffer.from([0]));
  } catch (e) {
    console.log(e);
