Javascript: Using a timestamp as a temporary ID # VS Using a counter as a temporary ID #
<p>I'm working on a project and we need a unique temporary number to identify a set of data.  I want to use the timestamp, my coworker wants to use a counter variable.  </p>

<p>Which approach is better?  My thought is less overhead as we just get the timestamp when the user clicks the add button when they want to add the set of data vs having to keep track of a counter.</p>

<p>Keep in mind, I'm new to web development and I am biased towards my own idea.</p>
