What are type parameters in TypeScript?

Type parameters in TypeScript allow you to create reusable components that can work with any data type. They are defined using angle brackets, like <T>, where T can be replaced with any type.

Can you give me an example of how to use type parameters?

Sure! Here's a simple example:

function identity<T>(arg: T): T {
    return arg;
}

This function takes an argument of type T and returns it, preserving the type.

What are the benefits of using type parameters?

Using type parameters enhances code reusability and type safety. It allows you to write functions and classes that can operate on various types without losing type information.

Are there any limitations to type parameters?

Yes, type parameters cannot be used with primitive types directly, and you need to ensure that the types used are compatible with the operations performed within the function.
