What are type parameters in programming?

Type parameters are placeholders in generic programming that allow you to define functions or classes with a flexible type.

Can you give me an example of how type parameters are used?

Sure! In a generic function, you might see something like function identity<T>(arg: T): T { return arg; }, where T is a type parameter.

Why are type parameters useful?

They promote code reusability and type safety, allowing you to write functions that work with any data type.

Are there any downsides to using type parameters?

One downside is that they can make code more complex and harder to read, especially for beginners.
