Hey Dwayne Munro, In 3rd task they only asked you to call function and assign return value to var yearToday

function getYear() {
  var year = new Date().getFullYear();
  return year;
}
var yearToday = getYear();

Hi there! You're doing great and you're on the right track. You set up the yearToday variable and then on a new line you call the getYear function. The getYear function is going to look up the current year and then send it back to the piece of code that called it. But you never do anything with the returned value. Take a look:

function getYear() {
  var year = new Date().getFullYear();
  return year;
}
var yearToday = getYear();

This last line does two things. It sets up our variable yearToday. Then it calls the getYear function. The getYear function will deterimine the year and send it back. That year now gets assigned as the value of our yearToday. Hope this helps! :smiley:
