I'm trying to make a code that will give the sum, average, min, max, and frequency of numbers in a list and also sorts the list from lowest value to highest value. With the help of others, I was able to get the sum, average, max, min, and frequency, but could not figure out how to sort the list from highest value to lowest value. What I want from the code is to have a button at the end of the code
.title { font-weight:bold; margin-top:1em; }<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<link rel="stylesheet" type="text/css" href="style.css">
<!--- This only allows the user to input numbers --->
<input type='number' id='input'>
<!--- This is the button that adds the number to the list --->
<input type='button' value='add to list' id='add' disabled="disabled">
<!--- Here we have a title for the list --->
<div class="title">Topics</div>
<!--- This will list all of the numbers --->
<ul id='list'></ul>
<!--- When clicked, this buttons alert the user with the numbers --->
<button id="sum"> Sum </button>
<button id="max"> Max </button>
<button id="min"> Min </button>
<button id="avg"> Avg </button>
<button id="frequency"> Frequency </button>
<div>
<button value="Refresh Page" onclick="window.location.reload()"> Reset! </button>
</div>

let list = document.getElementById("list");
let input = document.getElementById("input");
let add = document.getElementById("add");
var avg = 0;
var sum = 0;
var min = -Infinity;

let frequency = Object.create(null);
// This will add the input number to the list and clear the input
function addClick() {

// This will calculate and update all variable values

var count = 0;

// This functions will alert the numbers

function minClick() {
