States under the year parameter:

year
Integer value representing the year. The year must always be provided in full (e.g. 98 is treated as 98, not 1998).

However, that does not seem correct:

The description of the constructor is:
new Date(year, month [, day, hour, minute, second, millisecond]);

When creating a date like this:   
new Date(98, 1, 1) 

The result is Date {Sun Feb 01 1998 00:00:00 GMT+0000 (GMT Standard Time)}

The year displayed is 1998 not 98, which seems to be the opposite of what the parameter description states.

Added a screenshot showing the results of Date object creation when using the Date constructor new Date(year, month [, day, hour, minute, second, millisecond]);

Thanks for reporting this. I updated the parameter description and added a small example:
