When should I use types vs interfaces in TypeScript?

Can you explain when to use types versus interfaces in TypeScript?

Sure! In TypeScript, both types and interfaces can be used to define the shape of an object, but they have some differences.

What are the main differences between types and interfaces?

The main differences are that interfaces can be extended and implemented, while types cannot. Types can represent any valid TypeScript type, including primitives, unions, and tuples.

When should I prefer using an interface over a type?

You should prefer interfaces when you want to define a contract for classes or when you need to extend existing types. They are also more readable for object shapes.

Can I use both types and interfaces together?

Yes, you can use both together! For example, you can use a type to define a union and an interface to define an object shape.
