title: javascript functions with json object parameter
body: <p>If I have a number of functions that take json object parameters, does it make any difference whether I assign them to a variable before using them inside the function:</p>
  
  <pre><code>Function doSomething(data){
  var abc = data;
  
  abc.filter….etc.
  
  }
  </code></pre>
  
  <p>Vs.</p>
  
  <pre><code>Function doSomething(data){
  
  Data.filter….etc
  
  }
  </code></pre>
  
  <p>is one way better than the other?</p>
