await won't block Node from handling other requests but it will block the thread that is awaiting. For example, these will execute one after the other (the "bad way"):

  await slowThingOne();
  await slowThingTwo();
but these execute in parallel, awaiting until both are finished (the "good way"):

  await Promise.all([slowThingOne(), slowThingTwo()]);


Minor clarification, the latter example will only await until both have resolved *or* one rejects. To await the resolution of all promises, you should use the truly gamechanging `Promise.allSettled` , though you will have to transpile it if it's not supported by your target environments.
