"I’d say Angular is mostly being used by people from a Java background because its coding style is aimed at them. Unfortunately they aren’t trained to recognise Angular’s performance problems."
If I follow the logic correctly--people with Java backgrounds are not trained to recognize performance problems? Quite the curious line of reasoning.
It's specific to Angular running in the browser opposed to Java running on a server. You'll certainly run into different performance bottlenecks especially in long running client side applications. What works on the JVM will be very different than what works on the browser especially across multiple vendor's JS runtimes and versions.
