Hello everyone,,,
A couple of months ago I ported an old Delphi application to the web. It was the standard, classic, Windows desktop application, with windows to enter data, datatables, reports and so. It works, but I think that it's a bit clunky, as it's all server side renderer with Symfony 4 (PHP).

As an enhancement, I wanna port the frontend of this application to Javascript. I'm an experienced developer (more than 20 years programming), but I'm a novice with modern Javascript (I'm sorry, currently I only use jQuery... :P).

I've been doing some Angular and React tutorials, but these tutorials are very simple and easy, so I still don't know which of these frameworks is the more recommended for the kind of application I want to write. Can you help me to choose which framework to use?

Thank you! :)
