# TypeScript Generics Explained
Generics in TypeScript allow you to create reusable and type-safe components. Here’s a simple example:
function identity<T>(arg: T): T { return arg;}
console.log(identity<string>("Hello"));console.log(identity<number>(42));Generics can also be used with classes and interfaces:
class Box<T> { private content: T;
constructor(content: T) { this.content = content; }
getContent(): T { return this.content; }}
const stringBox = new Box<string>("TypeScript");console.log(stringBox.getContent());Generics are a powerful feature that can make your TypeScript code more flexible and maintainable.
