And of course many many websites using just HTML and JavaScript, then jQuery and finally React.

But not everything is about a language. I would probably not be able to ready what I did in early stages. The code was mess and I can remember I was angry with myself that the bigger the project is the more problems to understand its part I had. Maybe you know this quote:
