title: What is the difference between Proctractor and Selenium?
body: <p>I am in the stage to find out what is <a href="http://www.seleniumhq.org/" rel="nofollow">Selenium</a>. Its website looks very old. <a href="http://nightwatchjs.org/guide" rel="nofollow">Here</a> is a nodejs version of it. </p>
  
  <p>I also found a good in browser testing solution <a href="http://www.protractortest.org/#/" rel="nofollow">protractor</a>. </p>
  
  <p>Are they designed to do the same thing? Which one should I use? Why Selenium website is so old, out of favor? </p>
