title: Declaring two variable with the same name
body: <p>Is it possible to call the same name variables which set outside of the function?</p>
  
  <pre><code>var a = $(window).width(); // I want to call this variable
  if(!$.isFunction(p)){
      var a = $(window).height(); // Not this one
      alert(a);
  }
  </code></pre>
