title: What does the value attribute mean for checkboxes in HTML?
body: <p>Suppose this checkbox snippet:</p>
  
  <pre><code>&lt;input type="checkbox" value="1"&gt;Is it worth?&lt;/input&gt;
  </code></pre>
  
  <p>Is there any reason to statically define the <code>value</code> attribute of checkboxes in HTML? What does it mean?</p>
