Date.parse() — invalid string returns NaN

📖 Usage Example

Date.parse('2024-01-15T00:00:00.000Z')  // → 1705276800000
Date.parse('invalid')  // → NaN

Use Date.parse() to convert a date string into a millisecond timestamp, or detect invalid strings by checking for NaN.

Date.parse()

When given an unparseable string, Date.parse() returns NaN.

Challenge: Verify that Number.isNaN(Date.parse('invalid')) returns true.
