/**
 * The `$$` command is a short way to call the [`findElements`](/docs/api/webdriver.html#findelements) command in order
 * to fetch multiple elements on the page. It returns an array with element results that will have an
 * extended prototype to call action commands without passing in a selector. However if you still pass
 * in a selector it will look for that element first and call the action on that element.
 *
 * Using the wdio testrunner this command is a global variable else it will be located on the browser object instead.
 *
 * You can chain `$` or `$$` together in order to walk down the DOM tree. For more information on how
 * to select specific elements, see [`Selectors`](/docs/selectors.html).
 *
 * <example>
    :index.html
    <ul id="menu">
        <li><a href="/">Home</a></li>
        <li><a href="/">Developer Guide</a></li>
        <li><a href="/">API</a></li>
        <li><a href="/">Contribute</a></li>
    </ul>
    :$.js
    it('should get text a menu link', () => {
        const text = $$('#menu')[0];
        console.log(text.$$('li')[2].$('a').getText()); // outputs: "API"
    });
 
    it('should get text a menu link - JS Function', () => {
        const text = $$(function() { // Arrow function is not allowed here.
            // this is Window https://developer.mozilla.org/en-US/docs/Web/API/Window
            // TypeScript users may do something like this
            // return (this as Window).document.querySelectorAll('#menu')
            return this.document.querySelectorAll('#menu'); // Element[]
        })[0];
        console.log(text.$$('li')[2].$('a').getText()); // outputs: "API"
    });
 * </example>
 *
 * @alias $$
 * @param {String|Function} selector  selector or JS Function to fetch multiple elements
 * @return {Element[]}
 * @type utility
 *
