title: What is the priority of execution of javascript?
body: <p>I have an external JavaScript file linked by blogger. I want to change valuess in it. (css values assigned with JavaScript)</p>
  
  <p>Is it possible to run the same code in head or body with different values assigned with JavaScript?
  For example, CSS gives least priority to the external CSS stylesheets and assigns the properties which are given inside the file.</p>
  
  <p>Does JavaScript have any priority system like that?</p>
