title: What does the hook numbers in the Reactjs Dev tool correspond to?
body: <p>I have a react.js app that I want to profile for performance issues.</p>
  <p>I'm using the react dev tool profiler in firefox.</p>
  <p>I profile a specific interaction and get the flamegraph and the ranked time graph in the dev tool.</p>
  <p>Then this message shows up in the dev tool:</p>
  <p><a href="https://i.stack.imgur.com/0uu0V.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0uu0V.png" alt="enter image description here" /></a></p>
  <p>This part of the dev tool is not interactive, and I can't find anything on how the hooks are numbered.</p>
  <p>How do I interpret these numbers? What do they correspond to? Where can I find the information on what hooks they refer to?</p>
