How can I use generics in functions in TypeScript?

You can use generics in TypeScript to create reusable functions that work with any data type. For example, you can define a function like this: function identity<T>(arg: T): T { return arg; }.

Can you give me an example of how to use that function?

Sure! You can call the identity function with different types like this: let output1 = identity<string>('Hello'); or let output2 = identity<number>(42);.

What are the benefits of using generics?

Generics provide type safety, reduce code duplication, and allow you to create flexible and reusable components.

Are there any limitations to using generics?

Yes, generics can be complex, and sometimes they can lead to less readable code if overused. It's important to use them judiciously.
