title: Do the JavaScript web APIs run on a different thread than the call stack thread?
body: <p>At 12:16 in the following video by Philip Roberts, he talks about the Web APIs and Node APIs running on different threads than the call stack, if I am understanding him correctly? So, is this correct, do the Web APIs and Node APIs run on different threads than the call stack and event loop?</p>
  
  <p>If true, does this mean that they will run in parallel to JavaScript being executed in the call stack?</p>
