JS Practice — Built-in Objects

Date.now() — integer milliseconds

📖 Usage Example

const ts = Date.now()  // e.g. 1705276800000
typeof ts  // → 'number'

Use Date.now() to get the current time as milliseconds since the Unix epoch without creating a Date object.

Date.now()

The return value of Date.now() is always an integer (whole milliseconds).

Challenge: Verify that Number.isInteger(Date.now()) returns true.
