What are TypeScript type aliases?
TypeScript type aliases allow you to create a new name for a type. They can simplify complex types and improve code readability.
Can you give me an example of how to create a type alias?
Sure! You can create a type alias like this: type Point = { x: number; y: number; };
This defines a new type called Point
.
How do type aliases differ from interfaces?
Type aliases can represent any valid type, including primitives, unions, and tuples, while interfaces are specifically for object shapes.
When should I use a type alias instead of an interface?
Use type aliases for complex types or when you need to use union types. Interfaces are better for defining object structures.
