title: Difference between webdriverjs and webdriverio
body: <p>I am trying to choose a tool for Javascript automation tests.</p>
  
  <p>Until now I used Selenium WebDriver in Java with TestNG to build my tests, but I have been asked to search for JavaScript solution to write tests.</p>
  
  <p>Of course the first thing on my mind was to move to <a href="https://github.com/SeleniumHQ/selenium/wiki/WebDriverJs" rel="noreferrer">WebDriverJs</a> - it should be similar to my Java tests.</p>
  
  <p>But, I also found another framework: <a href="http://webdriver.io/" rel="noreferrer">WebdriverIO</a>. I could not find anything that could be done with WebdriverIO that is not possible with WebDriverJs.</p>
  
  <p>Please help me to understand the difference so I can choose the right framework for me.</p>
