title: What does 'is an instance of' mean in Javascript?
body: <p>The answer to this question:
  <a href="https://stackoverflow.com/questions/4073677/what-is-the-initial-value-of-a-javascript-functions-prototype-property">What is the initial value of a JavaScript function&#39;s prototype property?</a></p>
  
  <p>has this sentence:</p>
  
  <blockquote>
    <p>The initial value of prototype on any newly-created Function instance is a new instance of Object</p>
  </blockquote>
  
  <p>As far as I know, Javascript doesn't have classes and the word 'instance' therefor doesn't make sense in my head. How should one interpret 'instance' in Javascript?</p>
  
  <p>Sorry, I don't have enough rep to put my question in the comment thread on that answer.</p>
