It means you want only a Year from the entire date. For example: today is Saturday Jul 15 2017 [Day of the week, Month, Day, Year] and when you say to a program .getFullYear() it gives you only '2017' and doesn't give you month nor day.

I hope that's clear enough, don't hesitate to ask again though.

The Date object is used to work with dates and times.

Date objects are created with new Date().

The Date object is build-in to JavaScript so you can just use it. In this case you use it to get the current year, in fact you are getting full date in the moment you call it and this part ".getFullYear()" indicates you only want the year part of todays date
