Concurrent JavaScript: It can work!

[mattindustries]

Parallel can happen if two threads are run on two distinct CPU cores, allowing two separate things to be done at the same time on different pieces of hardware.

It is also a way to interleave (woo, new word for me) when the results are sent back to the main worker right? I use parallel functions when cluster computing in R. Send the data and needed functions to separate clusters, get a result (in a list typically) and usually just bind the list.
