I know C++, used to know Perl, and know JavaScript pretty well. The fact that you actually name WebSockets as a technology sort of sums up the issue we are discussing here. WebSockets is not something that can be compared to C++ or even Node. It's a dumb hack which justifies its existence primarily by allowing web apps to circumvent corporate firewall policies.

The web is a joke of an app platform. Those of us who have wider experience of different kinds of programmings see some web devs struggling with this concept and conclude, I think quite reasonably, that the only plausible explanation is lack of experience. This is not due to "outdated skills" - I daresay everyone criticising the web as a platform in this thread has, in fact, written web apps. It's the opposite problem. It's to do with developers who haven't got the experience of older technologies having nothing to compare it too, so "web 2.2" gets compared to compared to "web 2.0" and it looks like progress.

And in case you're tempted to dismiss me too, I recently tried to write an app using Polymer. It sucked. The entire experience was godawful from beginning to end. Luckily the app in question didn't have to be a web app, so I started over with a real widget toolkit and got results that were significantly better in half the time.
