The Composition API lets us create components without the need for a large single exportable object. It also has the added benefit of **compartmentalizing** code. With Vue 3, there was one way to create components in Vue. Vue 2 methodology is now known as the **[Options API* - the Composition and Options API are different. In the Options API, we can import something called 'ref' and use 'reactive' variables to create reactive variables.
