The main comment is probably too long. Maybe we can link out to the full docs from the JSDdoc widget? That could be neat.

Also, include the params in the JSDoc string?

With params:

And we don't need to specify RequestInit's fields, since it has its own JSDocs:

I tweaked it a bit

/**

 *
 * @param {string | URL} url - The URL to fetch
 * @param {RequestInit} [requestInit] - Optional configuration data (HTTP method, headers, etc) ([Docs ↗](https://deno.land/api@v1.42.1?s=RequestInit))
 */

I think we should also consider adding the type (ie string or RequestInit) in such a way that it shows up on hover or changing the product to render that info.
