Yes, thanks for pointing that out, and in fact I usually do implement it with push() to an array. I'm in slow-mo this morning as it's a dreary Saturday to start a long weekend :)

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
