So it’s the Y2K bug, but stupider.
As a sidenote: Did you know that the
Date
object in JavaScript has agetFullYear
method? It just gives you the year of the date. For instance:new Date(1995, 0, 1).getFullYear()
gives1995
.Why is it called getFullYear, you ask? Well, there’s also
getYear
, which only gives the last two digits of the year. For instance:new Date(1995, 0, 1).getYear()
gives95
. Not as useful as you might think, but ok.Now what happens in the year 2000? Guess. No, really. Do guess. And then guess again, because you’re wrong.
new Date(2024, 0, 1).getYear()
gives …drumroll… 124, not 24. After the year 1999 the counter just keeps incrementing.So what’s before 1900, then?
new Date(1776, 6, 4)
was, of course, the year −124.I think it’s worth noting that JavaScript isn’t an ancient language. It was developed in December 1995. The year 2000 wasn’t too far off.
