See, all the innovations are about code management and tracking. There has been nothing new for users for many years. In 2004 Gmail made AJAX popular and updating pages without reloading was a big deal. Later we had rounded corners, video without the Adobe Flash player, then came the websites that fit the screen size(the responsive web stuff) and later, we got some WebSocket stuff making possible real-time communications even snappier than AJAX.

That said, this is 15 years of time and the innovations came as browsers got better, IE died off but all these JS frameworks were always about making the codebase nicer.

Is there anything new for the users here? If not, why keep spawning new frameworks? Do these frameworks make anything better for the developers? In my experience, the JS world is a giant mess mostly because of the excess of frameworks that do the same things essentially.

That's why I felt burned out of web dev. I found out that all these frameworks that are supposed to make something easier to do are only making problems infinitely complex.

There's nothing new that you couldn't have done with 10 years old frameworks but now you need specialized knowledge on tons of tools.
