title: What does 'value is a reference' mean for JavaScript objects
body: <p>I was trying to understand passing of variables and objects in JavaScript, and came across <a href="https://stackoverflow.com/questions/518000/is-javascript-a-pass-by-reference-or-pass-by-value-language">this page</a>. <br/><br/>
  It is explained that JavaScript objects are passed by value, but the value itself is a reference. Though I understood what was happening in the examples given on that page, I am still confused so as to why. Can anyone please explain what does "value itself is a reference" mean?</p>
