title: Node.js selenium webdriver incognito mode
body: <p>I am having an hard time figuring out how to launch Selenium Webdriver for Chrome in incognito mode.</p>
  
  <p>I understand I need to pass the <code>--incognito</code> parameter to chromedriver, but how do I do that when creating the driver instance?</p>
  
  <p>This is how I am currently instantiating my driver object:</p>
  
  <pre><code>require("chromedriver");
  const webdriver = require("selenium-webdriver");
  const driver = new webdriver.Builder().forBrowser("chrome").build();
  </code></pre>
