Your serverless function cold-starts in 800 milliseconds. Your TypeScript build needs a separate step just to strip types. Every one of those costs is set the day you pick a JavaScript runtime — and switching later means rewriting import maps, permission flags, and Dockerfiles that nobody documented. In 2026 the choice is genuinely three-way: <strong>Node.js 24</strong> (the incumbent, now on its third decade), <strong>Bun</strong> (the all-in-one speed demon that bundles, transpiles, tests, and installs), and <strong>Deno</strong> (the security-first runtime built by Node&rsquo;s original creator). This guide compares them with live GitHub data, official install scripts, and production-tested Docker configurations so you can decide in ten minutes, not ten days.</p>
