// Explicit Types
let age: number = 30;
let name: string = "Alice";
let isAdmin: boolean = true;


// Type Inference (Better)
let count = 0; // inferred as number


// Array
let scores: number[] = [10, 20, 30];


// Object
interface User {
  id: number;
  name: string;
}
const user: User = { id: 1, name: "Bob" };
