Definition:Edge Runtime
Edge Runtime executes lightweight serverless JavaScript functions on CDN nodes located physically closest to the end user.
Detailed Technical Explanation
Business Perspective
Edge computing delivers near-instant personalized web experiences globally.
Technical Perspective
Operates with strict memory limits, supporting Web Standard APIs (`fetch`, `Request`, `Response`).
Real-World Example
Executing user geolocation redirects and A/B testing header logic at the edge node before page rendering.
Common Architectural Mistakes
