Hi, good article!

In this snippet you are missing some keywords.

function functionBasedNotificationFactory() {
	type: 'Success',

	 notifyUser() {
		console.log(`${type} notification`);
	}

	return {
		name: 'Success',
		notifyUser: delayMiliseconds(notifyUser, 300);
	}
}

function functionBasedNotificationFactory() {
	const type = 'Success'

	function notifyUser() {
		console.log(`${type} notification`);
	}

	return {
		name: 'Success',
		notifyUser: delayMiliseconds(notifyUser, 300)
	}
}
