A naive approach to implementing the Ordered Server Counter

	import material from 'materialize-css/dist/js/materialize';

	let count = 0;

	// Server simulation
	async function processCommand() {
	count += 1;
	return count;
	}

A synchronized solution to the Ordered Server Counter Example

	import { Mutex } from 'async-mutex';
	import material from 'materialize-css/dist/js/materialize';

	let count = 0;
	let clientLock = new Mutex();

	// Server Simulation
	function processCommand() {
	count += 1;
	return count;
