You can't do every aspect of everything well, I would say it is even foolish to try. If you want to try out react.js (for example), make a shitty skeletal HTML file, put in a script tag, and start doing stuff. The app doesn't have to run in a well-managed hosted environment with a cool hostname and all that. Don't make build scripts, etc., until you have to.

There is a time for best practices but you shouldn't focus on the best practices for things that are ancillary for what you're really trying to learn. This is what focusing is all about, paying attention to what's important and disregarding the rest. Don't dick around with editor configs.
