title: What does enumerable mean?
body: <p>I was directed to MDN's <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in" rel="noreferrer">for..in page</a> when it said, "for..in Iterates over the enumerable properties of an object."</p>
  
  <p>Then I went to the <a href="https://developer.mozilla.org/en-US/docs/Enumerability_and_ownership_of_properties" rel="noreferrer">Enumerability and ownership of properties page</a> where it said "Enumerable properties are those which can be iterated by a for..in loop."</p>
  
  <p>The dictionary defines enumerable as countable, but I can't really visualize what that means. Could i get an example of something being enumerable?</p>
