I basically followed that approach with my web (browser) extension: Started with the absolute basics (HTML, CSS, vanilla JS) and slowly ran into situations where I needed more modern features – notably file splitting/imports and types to manage the growing and repetitive JS code. The approach worked for me and I learned some neat things about vanilla CSS and JS features, but I would also rather start new projects with a boilerplate or framework, because even small projects easily grow in scope and it’s nice to be prepared for the eventuality.
