<ul><li>Edge computing processes data near its source or end user, reducing latency and improving scalability by deploying applications to edge nodes.</li><li>JavaScript has become a powerful tool for edge computing through platforms like Node.js and edge-optimized runtimes such as Cloudflare Workers, Deno Deploy, and Vercel Edge Functions.</li><li>A simple geolocation-based greeting service example using Cloudflare Workers demonstrates how JavaScript can run on edge servers to handle requests closer to users, improving performance.</li><li>Emerging standards like WebAssembly System Interface (WASI) are enabling non-JavaScript languages to run on the edge, while Cloudflare Workers, with its global network and free tier, remains a popular choice for edge computing with JavaScript.</li></ul>
