title: What is the DOM Node Count in google chrome's developer tools timeline memory view?
body: <p>I'm getting an "Aw, snap!" chrome crash when a certain webpage is being loaded. I'm trying my best to figure out what's causing it and having a really hard time.</p>
  
  <p>In the Chrome Developer's tool there is a Memory Tab and when looking at the counter graphs, I notice that the DOM Node Count line steps up, drops, and then continues to rise.</p>
  
  <p><img src="https://i.stack.imgur.com/Zp3qG.png" alt="Dom node count increasing"></p>
  
  <p>I understood this to mean that the DOM element counts on my page were increasing but after doing </p>
  
  <pre><code>document.getElementsByTagName("*").length
  </code></pre>
  
  <p>in the console I noticed the value wasn't changing.</p>
  
  <p>So what is the DOM Node count graph actually showing? If it continues increasing like this, could that potentially be the cause of the "Aw, snap!" crash?</p>
