I love these type of showcases. It‘s been a wonderful time when simply upload files via SFTP and had a running application. No need of webpack bundles, vendor libraries to achieve a simple functionality that could be solved in a few lines of code ... I really do hope this kind of developer attitude (writing pure VanillaJS) is coming back.
There's a reason why a lot of those libraries and tools are used though. Webpack bundles are used to strip down multiple JS files and libraries into a single bundle that contains only what is needed to run a particular application. Libraries like React serve a purpose too, particularly when you're building large applications that need to be maintained by many people all at once, or when you need insane compatibility…
