title: What is the "leak" of object properties in Javascript (chrome dev tool)?
body: <p>I'm debugging a memory leak in my javascript code using the chrome developper tool and the <a href="https://docs.google.com/presentation/d/1wUVmf78gG-ra5aOxvTfYdiLkdGaR9OhXRnOlIcEmu2s/pub?start=false&amp;loop=false&amp;delayms=3000#slide=id.g31ec7af_0_58" rel="nofollow noreferrer">Google's 3 snapshot techniques</a> which i can't recommand enough.</p>
  
  <p>However, now, by looking at the objects allocated between snapshot 1 and 2 in the snapshot 3's view (thoses are leaked objects, if you read the slides), i'm seeing a big bunch of "object properties".</p>

  <p>What does it mean ?</p>
  
  <p>Does it means that i added some properties (between snapshot 2 and 3) in thoses objects that weren't existing in snapshot 1 and i didn't delete ?</p>
