Some nifty JS script that can be used to sort a dictionary <python> or rather Object <javascript> by one of the values in the Object

sort_dict.js

//init a dict with key value pairs. The values in my case are arrays. That can be changed
var dict = {
    "x": [1, 3],
    "y": [6, 90],
    "z": [9, 16],
    "a": [5, 3],
    "b": [7, 9],
    "c": [11, 3],
    "d": [17, 3],
    "t": [3, 10]
};

// Create items array
var items = Object.keys(dict).map(function(key) {
    return [key, dict[key]];
});


// Sort the array based on the second element
items.sort(function(first, second) {
    return second[1][0] - first[1][0];
});

// Create a new array with only the first 8 items
console.log(items.slice(0, 8));
alert(items.slice(0, 8))
