What is the difference between type and interface in TypeScript?

What is the difference between type and interface in TypeScript?

In TypeScript, both 'type' and 'interface' can be used to define the shape of an object, but they have some differences. 'Interface' is primarily used for defining object shapes and can be extended or implemented, while 'type' can define more complex types, including unions and intersections.

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

Sure! Use 'interface' when you want to define a contract for classes to implement. Use 'type' when you need to create a union type or when defining a more complex type that includes primitives.

Are there any performance differences between using type and interface?

No, there are no significant performance differences between 'type' and 'interface' in TypeScript. The choice between them is more about code organization and readability.

Can I use both type and interface in the same project?

Absolutely! You can use both 'type' and 'interface' in the same project. It's common to use 'interface' for object shapes and 'type' for more complex types.
