Just to place things right:
ANGULAR IS NOT DEAD!
(I don’t know why so many think it will end on Dec 2020)
The discussion would be similar to OH NO! PHP WILL BE NO LONGER SUPPORTET. Oh it’s just PHP6.
Angular just gets a new naming:
“Angular is the name for the Angular of today and tomorrow.
AngularJS is the name for all 1.x versions of Angular.”
So when Louis Reingold says “Oxygen won’t be rewritten in another framework” he DOES NOT say that they don’t upgrade to Angular.
