/**
 *
 * The `react$` command is a useful command to query React Components by their
 * actual name and filter them by props and state.
 *
 * **NOTE:** the command only works with applications using React v16.x
 *
 * <example>
    :pause.js
    it('should calculate 7 * 6', () => {
        browser.url('https://ahfarmer.github.io/calculator/');
 
        browser.react$('t', { name: '7' }).click()
        browser.react$('t', { name: 'x' }).click()
        browser.react$('t', { name: '6' }).click()
        browser.react$('t', { name: '=' }).click()
 
        console.log($('.component-display').getText()); // prints "42"
    });
 * </example>
 *
 * @alias browser.react$
 * @param {String} selector of React component
 * @param {Object=} props  React props the element should contain
 * @param {Array<any>|number|string|object|boolean=} state  React state the element should be in
 * @return {Element}
