title: How to find a string that is used in javascript files in a web page
body: <p>There is a web page that loads multiple javascript files.</p>
  
  <p>And I want to search for a string for in all files like a <code>grep</code>.</p>
  
  <p>Of course I can grep them if I download all the files, but I'd rather search them using development tools in a web browser.</p>
  
  <p>Is there a easy way to search all javascript files that are loaded by a web page for a string?</p>
