Interesting Node sleep() Function

NodeJS

Today I had a reason to look at some Node issues with async processing, and ran across these two little functions that are interesting, but quite deadly. They pause the Node Runtime for the specified number of milliseconds, or seconds, and this is nice - when you have to have a delay, but all Node processing stops. This means all the async calls won't get processed, either.

  function msleep(n) {
    Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), 0, 0, n);
  }
 
  function sleep(n) {
    msleep(n*1000);
  }

Simple. Easy. But not really what I was looking for. 🙂
