      PhantomJS is a headless WebKit with JavaScript API.
      It has fast and native support for various web standards:
      DOM handling, CSS selector, JSON, Canvas, and SVG.

      PhantomJS is an optimal solution for:
      - Headless Website Testing
      - Screen Capture
      - Page Automation
      - Network Monitoring
