title: Does registering event handlers consume much resources?
body: <p>Does the amount of resources needed to register an event handler grow proportionally to the number of elements in the selected object?</p>
  
  <p>For example in the following:</p>
  
  <pre><code>$('.emoji').click( ..... );
  </code></pre>
  
  <p>If there are 4000 elements with the class emoji, would the memory used up in the browser be significantly higher?</p>
