The result of Number('0x10') is 16. The Number() function recognizes the '0x' prefix as indicating a hexadecimal number. In hexadecimal, '10' represents the decimal number 16 (1×16¹ + 0×16⁰). This is one of the special parsing rules for the Number() function. Similarly, Number('0b1010') would return 10 (binary), and Number('0o10') would return 8 (octal). This behavior differs from parseFloat(), which does not recognize these prefixes and would interpret '0x10' as just 0.
