What are interfaces and types in TypeScript?

In TypeScript, interfaces define the structure of an object, while types can define both primitive and complex types.

Can you give me an example of an interface?

Sure! Here's a simple interface example: interface Person { name: string; age: number; }.

How do types differ from interfaces?

Types can represent any valid TypeScript type, including unions and intersections, while interfaces are specifically for object shapes.

When should I use an interface instead of a type?

Use interfaces when you want to define object shapes and extend them, and types when you need more flexibility with unions or primitives.
