Do you have experience using generics in programming?

Generic types (Generics) allow creating components that work with different data types while maintaining type safety and ease of use.

In the context of Node.js (JavaScript/TypeScript), generics are implemented in TypeScript. For example, you can write a function that works with an array of any type:

function identityArray<T>(items: T[]): T[] {
    return items;
}

const numbers = identityArray<number>([1, 2, 3]);
const strings = identityArray<string>(["a", "b", "c"]);

In JavaScript without TypeScript, generics are not present as such, but dynamic typing can be used.

If you have experience with TypeScript, using Generics helps write more versatile and type-safe code.
