Use WebWorkers and promises to run sync heavy functions in a worker (process) and get the result in a promise

	function asyncThread(fn, ...args) {
	if (!window.Worker) throw Promise.reject(
	new ReferenceError(`WebWorkers aren't available.`)
	);

	const fnWorker = `
	self.onmessage = function(message) {
	(${fn.toString()})
	.apply(null, message.data)
	.then(result => self.postMessage(result));
