What are generics in programming functions?

What are generics in programming functions?

Generics allow you to write flexible and reusable functions that can work with any data type.

Can you give me an example of a generic function?

Sure! Here's a simple example in TypeScript:

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

This function takes an argument of any type and returns it.

How do generics improve code quality?

Generics enhance type safety, reduce code duplication, and improve maintainability by allowing functions to operate on various types without losing type information.

Are there any downsides to using generics?

One downside is that they can make code more complex and harder to read for those unfamiliar with generics.
