title: Do javascript arrays and objects have a set order?
body: <p>This question is vital to one of my current projects involving creating HTML tables from JSON objects. I was thinking I could create functions that would sort my Arrays/Objects before rendering them as HTML. My only concern is that order doesn't matter in JavaScript, and if I were to create a new <code>Array</code> with the same data (in a different order) as another <code>Array</code> they would end up identical.</p>
  
  <p>I can't think of a fast way to test this, so I'm asking here.</p>
