Footnote – a version of the cellTextMD function which picks up inline links as Markdown links, and also catches fonts with either ‘Oblique’ or ‘Italic’ in their name for the single-star Markdown emphasis.

    // cellTextMD :: OO.Cell -> String
    const cellTextMD = cell => {
        const as = cell.richText.attributeRuns;
        return zipWith3((txt, fnt, style) => {
                const
                    bld = any(contains(fnt), ['Bold', 'Black']) ? (
                        '**'
                    ) : '',
                    ital = any(contains(fnt), ['Oblique', 'Italic']) ? (
                        '*'
                    ) : '',
                    url = style.attributes.byName('link')
                    .value();
                return bld + ital + (
                    isNull(url) ? txt : ('[' + txt + '](' + url + ')')
                ) + ital + bld;
            }, as.text(), as.font(), as.style())
            .join('');
    };

It uses a generic zipWith3(f, xs, ys, zs) function, which can be defined as:

    // zipWith3 :: (a -> b -> c -> d) -> [a] -> [b] -> [c] -> [d]
    const zipWith3 = (f, xs, ys, zs) =>
        Array.from({
            length: Math.min(xs.length, ys.length, zs.length)
        }, (_, i) => f(xs[i], ys[i], zs[i]));

Apart from isNull() the other generic functions are given in the original listing in this thread

    // isNull :: [a] | String -> Bool
    const isNull = xs =>
        Array.isArray(xs) || typeof xs === 'string' ? (
            xs.length < 1
        ) : undefined;
