title: jQuery 3.0 removeAttr vs. prop
body: <p>I just read jQuery 3.0's breaking changes, and I think this should be known by all front-end engineers.</p>
  
  <p>e.g. Questions, 
  1. how to uncheck a checkbox?
  2. how to remove checked from radio button?</p>
  
  <pre><code>$('input').prop('checked', false);
  </code></pre>
