$$ command is a short way to call the
findElements command in order
to fetch multiple elements on the page. It returns an array with element results that will have an
extended prototype to call action commands without passing in a selector. However if you still pass
in a selector it will look for that element first and call the action on that element.
Using the wdio testrunner this command is a global variable else it will be located on the browser object instead.
You can chain
$$ together in order to walk down the DOM tree.
For more information on how to select specific elements, check out the Selectors guide.
