JS Practice — Built-in Objects

Interface — createUser

📖 Usage Example

interface User { name: string; age: number }
const u: User = createUser('Alice', 30)
// → { name: 'Alice', age: 30 }

An interface defines the required shape — any object with matching properties satisfies it.

Interfaces: Basic Shape

Interfaces define the shape of an object. TypeScript uses structural typing — any object with matching properties satisfies an interface.

Challenge: Implement createUser(name, age) returning an object with name: string and age: number.

createUser('Alice', 30)  // → { name: 'Alice', age: 30 }
