Meanwhile, in VS Code etc you can just hover over something and click to go directly to it, which is cool, but it's kind of like teleporting instead of actually driving to the destination enough to learn the roads.
I do a similar thing with git PRs -- for example, if you build something that follows a bundled pattern (ex. a component that has frontend, backend and data-related files, plus naming conventions), having a clean + complete reference PR to revisit when you make new components helps ensure I don't miss anything and stay consistent. I usually view these in-browser since Github/Bitbucket/Gitlab all have nice interfaces to see what files you need, where they go, how they're named, etc.
Plus it's written in rust and as we know, it's blazingly fast.
That blog is eight years old now, but still pretty accurate.
