What are you on about? Concurrent programming is the set of problems that exists when there are multiple 'computational processes' accessing shared state. This is a 'thread' (overloaded use) about JS, but Java has a package called java.util.concurrent and there's also a seminal book called "concurrency in practice", these are about nothing but threads.

Parallelism is just a new buzz word for people who have just discovered that threads\processes exist and they can have multiple things running at the same time. They just removed the shared state cause they don't want to have to deal with the headaches of concurrent programming.
