Array.of() — mixed-type array

📖 Usage Example

Array.of(1, 'two', true, null)
// → [1, 'two', true, null]

Array.of() accepts values of any type and places them all in a new array.

Array.of() — heterogeneous elements

Array.of() works with any mix of value types. The resulting array's type is the union of its element types.

Challenge: Implement createMixed that takes a number, string, boolean, and null and returns them in an array using Array.of.

createMixed(1, 'two', true, null) // → [1, 'two', true, null]
