Type Unions and Intersections
In TypeScript, you can define a type that can be one of several types using a union type. This is beneficial when an entity can reasonably be one of several types.
type StringOrNumber = string | number;
Intersection types allow you to combine multiple types into one, enabling objects to have properties of all intersected types.
type Name = { name: string };
type Age = { age: number };
type Person = Name & Age;
Exercise
Define a union type named Vehicle which can be either Car or Bike. The Car type has properties type and doors, while the Bike type has properties type and hasBell. Create a function that takes a Vehicle as an argument and returns whether it's a Car or Bike.
