title: How to get the HTML code after the browser execute javascript?
body: <p>I have problem in retrieving the HTML code containing JavaScript. </p>
  
  <p>What I expect is the HTML code in which the JavaScript has been executed and only pure HTML in it like the output of browsers(e.g. Chrome).</p>
  
  <p>I mean I hope that there is a Linux command or a way downloads HTML, execute JavaScript and output the page. (curl can download the page, but cannot execute the JavaScript)</p>
