title: How to iterate large arrays in NodeJS
body: <p>If I have to do iterations of large sets of data in Node, what are some precautions that I can take in an attempt to avoid making the server less responsive to other requests?
  The amount of time it takes for the iteration to finish is not of crucial importance to me, should I look into something like <a href="https://stackoverflow.com/questions/10344498/best-way-to-iterate-over-an-array-without-blocking-the-ui">this</a> or are there any other similar tricks that I should know about?</p>
