    simpler in es6:

    function arrayManipulation(n, queries) { let arr = new Array(2*n).fill(0); let max = 0;

    queries.forEach((item) => {
    arr[item[0]] += item[2];
    arr[item[1] + 1] -= item[2];
});

arr.reduce((prev, curr, idx) => {
    const sum = prev + curr;
    if (sum > max) {
        max = sum;
    }

    return sum;
})

return max;

    }
