JS Practice — Built-in Objects

Generics — unique<T>

📖 Usage Example

unique([1, 2, 2, 3, 3, 3])   // → [1, 2, 3]
unique(['a', 'a', 'b'])       // → ['a', 'b']

unique<T> removes duplicates by passing the array through a Set, preserving insertion order.

Generics: unique<T>

Challenge: Implement unique<T>(arr: T[]): T[] returning only the distinct values, preserving order.

unique([1, 2, 2, 3, 3])  // → [1, 2, 3]
unique(['a', 'b', 'a'])  // → ['a', 'b']
