Have you had experience using or working with generics in programming?

Generics are a mechanism that allows creating components (functions, classes) with type parameters, which increases code reusability and safety.

In the context of Node.js, which uses JavaScript, generics are not directly supported because JavaScript is a dynamically typed language. However, if you use TypeScript (a superset of JavaScript), generics are available and widely used.

Example of a function with a generic in TypeScript:

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

const num = identity<number>(42); // num will be of type number
const str = identity<string>("hello"); // str will be of type string

Using generics allows writing more versatile and type-safe code, for example, for working with collections or data wrappers.
