Answer 1

here is my solution!

// innerWidth
const screen_viewport_inner = () => {
    let w = window,
        i = `inner`;
    if (!(`innerWidth` in window)) {
        i = `client`;
        w = document.documentElement || document.body;
    }
    return {
        width: w[`${i}Width`],
        height: w[`${i}Height`]
    }
};


// outerWidth
const screen_viewport_outer = () => {
    let w = window,
        o = `outer`;
    if (!(`outerWidth` in window)) {
        o = `client`;
        w = document.documentElement || document.body;
    }
    return {
        width: w[`${o}Width`],
        height: w[`${o}Height`]
    }
};

// style
const console_color = `
    color: rgba(0,255,0,0.7);
    font-size: 1.5rem;
    border: 1px solid red;
`;



// testing
const test = () => {
    let i_obj = screen_viewport_inner();
    console.log(`%c screen_viewport_inner = \n`, console_color, JSON.stringify(i_obj, null, 4));
    let o_obj = screen_viewport_outer();
    console.log(`%c screen_viewport_outer = \n`, console_color, JSON.stringify(o_obj, null, 4));
};

// IIFE
(() => {
    test();
})();
