Techniques for inspecting the contents of opaque Headers objects in Cloudflare Workers by converting them into Maps, arrays, or plain objects for console logging and stringification.
When To Use
Use when you need to debug or inspect the key-value pairs within a request or response Headers object that appear empty when logged directly to the console.
