JS Practice — Built-in Objects

getFullYear() — result is a number

📖 Usage Example

const d = new Date(2024, 0, 15)
d.getFullYear()  // → 2024

Use getFullYear() to retrieve the four-digit year of a Date object in local time.

Date.prototype.getFullYear()

The return type of getFullYear() is always a primitive number.

Challenge: Verify that typeof new Date(2024, 0, 15).getFullYear() returns 'number'.
