How do I use generics with interfaces in TypeScript?

Can you explain how to use generics with interfaces in TypeScript?

Sure! Generics allow you to create reusable components that can work with any data type. In TypeScript, you can define a generic interface like this: interface Box<T> { content: T; }.

What does the <T> mean in that example?

The <T> is a placeholder for the type that will be specified when the interface is used. It allows the Box interface to be flexible.

Can you show me an example of how to use this Box interface?

Absolutely! You can create a Box for a string like this: const stringBox: Box<string> = { content: 'Hello' }; and for a number like this: const numberBox: Box<number> = { content: 42 };.

What are the benefits of using generics?

Generics provide type safety, reduce code duplication, and improve code readability by allowing you to define functions and classes that work with any data type.
