Answer 1

In case you were wondering how to find median without using conditionals, here you are :)

Mind ES6.

/**
 * Calculate median of array of numbers
 * @param {Array} arr
 * @return {Number}
 */
function median(arr) {
    arr = [...arr].sort((a, b) => a - b);
    return (arr[arr.length - 1 >> 1] + arr[arr.length >> 1]) / 2;
}

To answer the question:

median(data.map(x => x.values));
