What are the differences between types and interfaces in TypeScript?

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

Can you explain those key differences?

Sure! Interfaces are extendable, meaning you can create new interfaces based on existing ones, while types cannot be extended in the same way.

Are there any other differences I should know about?

Yes! Types can represent primitive types, unions, and tuples, while interfaces are specifically for object shapes.

It depends on your needs. Use interfaces for object-oriented designs and types for more complex type definitions.
