Opened this to do the work but I'm still not clear on the "zero dependency" concept and what falls in or out of that requirement.

Can you fix the compilation issue with the documentation?

Sorry I didn't comment that I'm going to change the JS example to actually run in the browser per the mdoc example.

I created an example that uses ZIO and ZIO Clock. It runs locally in a demo app but mdoc:js is using a different version of ScalaJS than the ZIO build. I think that's causing the build fail issues. Do you have any SBT experts that can get the code to compile on mdoc?

Started a PR to update mdoc to ScalaJS 1.1.1 but the Linker API has changed significantly and I will need additional help from someone familiar with ScalaJS to complete that Pull Request.
scalameta/mdoc#365

Do we think this will be fixed in the short term? Otherwise we could merge without mdoc and do that in a follow up.

@adamgfraser Since this is my first ZIO program, could you review that you like the actual code in the JavaScript example? I wanted to:

1. Give a good example of Scala.JS code.
2. Give a good example of ZIO code.
3. Use a Clock example since that's what we're enabling.
4. Use Console to show that it goes to the browser log.
5. Show it in the website.
   1. This is the magic node reference that mdoc provides.
   2. My local copy had a getElementById assigning node.
   3. This is disabled until PR Activate mdoc on JavaScript. #3974 comes through.

Do we think this will be fixed in the short term? Otherwise we could merge without mdoc and do that in a follow up.

I broke it out.

Sorry @adamgfraser. Ran short on time to finish the clean up. I'm still looking at the mdoc upgrade stuff. Hopefully I'll have more soon.
