This is good for practice and learning but honestly what is the point of going backwards. Some of these demos don’t even work on safari in mobile. Frameworks ar

  Most of these didn't work on Firefox either or fail gracefully, so no cross-browser support. I'd say that the more "stuff" you need to do on a web app, the more likely those features will need to be cross-browser compatible, and having done that in the past, I can say that VanillaJS is a fine thing for simple straightforward web apps, but when you start needing more features, it can be a load-off to outsource it to a framework. If you understand what the framework is doing, used sparingly, some frameworks can save you some time. JS libraries have the same deal, there are some features that I would prefer not rewrite every time I write an app. For instance, PDF.js is quite indispensable at reading PDFs in the browser and I think someone would spend quite a bit of time re-writing all the features you need from that library. Anyways, I guess it just all comes down to using the right tool for the job.
