Info

This test case shows the amount of overhead, if any, incurred when accessing data from localStorage directly compared to assigning the localStorage data to a variable and accessing the variable, as well as getting the value from a pre-populated select element.

Preparation code

<select id="test">
  <option>A</option>
  <option selected="selected">B</option>
  <option>C</option>
</select>
<input id="output" />
<script>
  localStorage['answer'] = 'B';
  var oSel = document.getElementById('test'),
      oOut = document.getElementById('output'),
      sAns = localStorage['answer'];
</script>
