title: Iteration Vs. Enumeration
body: <p>For iteration, I know there are different types of iterators E.g. Forward, Bidirectional, Random Access that can be used to access items in an array.</p>
  
  <p>For enumeration, I've only heard about enums that can be used to index items. But are there terms called 'enumeration' or enumerator? If so then, What's the difference between iteration and enumeration?</p>
