title: jQuery Hide/Show if conditional statement
body: <p>I do this a lot:</p>
  
  <pre><code>var condition = true;
  if (condition === true) {
      $('#condition_dependancy').show();
  } else {
      $('#condition_dependancy').hide();
  }
  </code></pre>
  
  <p>Can this be any cleaner syntactically? I could write my own:</p>
  
  <pre><code>$('#condition_dependancy').hidden(condition);
  </code></pre>
  
  <p>But i'm just wondering if there is anything built in.</p>
