Good concept. Unfortunately, I immediately ran into some permissions and configuration issues trying to install the very first script. A troubleshooting section would be helpful right there since once you get it working, the rest of the article would likely work.

Those are all good strategies. One more to mention would be the relatively modern Combine framework with it's publish/subscribe model.

To be super pedantic (which I am): grep is really: Global search for Regular Expression and Print matches.

A good introduction. I'm a big fan of using querySelector() rather than the older getElementById(), getElementByTagName(), and so on.
