    JavaScript (Node.js) Solution

    function equalStacks(h1, h2, h3) {
    let sum1 = h1.reduce((accumulator, currentValue) => accumulator + currentValue);
    let sum2 = h2.reduce((accumulator, currentValue) => accumulator + currentValue);
    let sum3 = h3.reduce((accumulator, currentValue) => accumulator + currentValue);
    let m;
    while (sum1 !== sum2 || sum2 !== sum3) {
        m =  Math.max(sum1, sum2 ,sum3);
        if (m === sum1) {
            sum1 -= (h1.shift());
        } else if (m === sum2) {
            sum2 -= (h2.shift());
        } else if (m === sum3) {
            sum3 -= (h3.shift());
        }
    }
    return sum1;
