What is Combining Types?
Combining types in TypeScript allows you to create new, more complex types from existing ones. This is achieved through features like unions and intersections. A union type lets a variable hold values of different types, while an intersection type combines multiple types into a single type that has all the properties of each individual type. These mechanisms provide flexibility and expressiveness when defining the shape of your data.
