We used to be in an era where Java developers had JSF and .NET developers had Webforms - two technologies that were the perfect storm for component vendors. This is all falling apart now that we have npm and webpack - and the only thing Java or .NET are good for is the REST service infrastructure they provide. No company should be using Webforms or JSF type technologies anymore.
So we've gone from using components with lifecycles - in the form on JSF and Web Forms, to using components with lifecycles - in the form of React and Angular.
I'm not knocking React or Angular - I use and enjoy them both. And I find it much more convenient to have components that live entirely in the browser instead of trying to maintain a stateful UI server-side; I certainly don't find Web Forms or JSF development to be very enjoyable.
I just find it mildly amusing that front-end web development seems to continually re-discover old concepts. That's certainly not a bad thing; better to re-discover good old concepts than to forget them completely.
I do wish they would remember some of the previous shortcomings, though.
In a way, I feel like security teams have it easy. Just look at whatever vulnerability worked 5 years ago on old frameworks. Solid chance it is easily exploitable on frameworks getting going today.
