title: Calling render vs painting the DOM?
body: <p>I’m learning about React and trying to get a better understanding about the lifecycle and about the different stages.</p>
  
  <p>One thing I just read states “React first renders and then mounts elements. Rendering in this context means calling a class’s render(), not painting the DOM”</p>
  
  <p>I guess I just don’t really get what that means. Can someone explain it in a simple way or with examples?</p>
  
  <p>Thanks in advance!</p>
