title: Difference between JQuery.type and typeof, which is faster
body: <p>I have a method called processData, in which i have used the below code to check the type of the variable</p>
  
  <pre><code>typeof series.dataSource.xName == "string"
  
  jQuery.type(series.dataSource.xName)=="string"
  </code></pre>
  
  <p>i what to know which is faster, and will take less time to execute, overall "type" need 55ms to execute, i need to optimize it</p>
  
  <p>Thanks in advance</p>
