title: React Hooks Refs
body: <p>So I decidet to rewrite my React Class Component into React Hook Component,
  And in my Class Component I did</p>
  
  <pre><code>&lt;canvas ref='canvas'&gt;&lt;/canvas&gt;
  </code></pre>
  
  <p>This approach didn't work anymore. How should I use refs then? In documentation only said that refs are still work.</p>
  
  <p>Thank you!</p>
