I’m by no stretch of the imagination a modern web developer. I know plain JS well, HTML and enough CSS/Bootstrap to throw together an internal website.

Even then most of my experience is with server side rendering.

However, for any large project, I would much rather be forced into using a modern framework than not. Any web app that is large enough is going to have some type of bespoke framework that was created by the “architect” who has been there forever.

It’s just like dealing with a bespoke ORM, logging, or authentication/authorization framework.
