What is the difference between types and interfaces in TypeScript?

What is the difference between types and interfaces in TypeScript?

In TypeScript, both types and interfaces can be used to define the shape of an object. However, interfaces are specifically designed for object shapes and can be extended, while types can represent any valid TypeScript type, including primitives, unions, and intersections.

Can you give me an example of when to use an interface over a type?

Sure! Use an interface when you want to define a contract for an object that can be extended or implemented by classes. For example, if you have a base shape and want to create more specific shapes, interfaces are ideal.

Are there any performance differences between using types and interfaces?

Generally, there are no significant performance differences between types and interfaces in TypeScript. The choice often comes down to readability and maintainability of your code.

Can I use both types and interfaces together?

Yes, you can use both types and interfaces together in TypeScript. They can complement each other, allowing you to leverage the strengths of both.
