🟦 TypeScript Generics

Generics make your code more flexible by allowing it to work with any type while preserving type safety. Think of them as "type variables" you can reuse in classes, functions, and interfaces.

📚 Example Code: Generic Function

Console output will appear here...

💡 Use angle brackets <T> to declare a generic type. It can be named anything — T, U, ItemType, etc.

🔧 Generic Function Syntax

<T> defines a type placeholder
When calling the function, you can explicitly specify the type like identity<string>("text"), or let TypeScript infer it
Generics maintain type safety while allowing flexibility

📦 Generic Classes Example

class Box {
  value: T;
  constructor(value: T) {
    this.value = value;
  }
  getValue(): T {
    return this.value;
  }
}

const numberBox = new Box(123);
console.log(numberBox.getValue());

⚡ You can use generics in functions, classes, and interfaces for reusable, strongly-typed code.
