It is correct. Angular, aurora: they all do the same.

The counter-argument is: why reinvent the weel ? To come up with something
as mature as react or Vue.js or angular would take a huge effort.

At least Vue.js is very stable in it's API.

No, they do not. It's a completely different paradigm, although one could
argue that the "webcomponent" approach is of course what Delphi does since
day 1, so we've come full circle.

Just confirms my opinion that nothing really new appeared in IT in the last 30
years. More of the same, but bigger and faster :)
