title: p5.js manually call setup and draw
body: <p>I am making an online game with p5.js and I would like to manually call setup, and once setup is called I want draw() to run.</p>
  
  <p>For example, if I click a button:</p>
  
  <pre><code>&lt;button id="somebutton" onclick="setup()"&gt;CLICK ME!!!&lt;/button&gt;
  </code></pre>
  
  <p>Then the canvas will be created and all of the stuff in setup will be run and draw() will run.</p>
