What does the intersection `type Admin = User & { role: 'admin' }` give you?

✓Correct answer: A type with all the properties of User plus role: 'admin'
2A type with only the properties common to User and the object with role
3A type that can be either User or { role: 'admin' }

Explanation

An intersection combines requirements: the value must satisfy both types. It's a way to compose types, similar to interface Admin extends User. Conflicting properties produce never for that property.
