The first step is to create the empty function: 

function getYear(){}

Step two add the line var year = new Date().getFullYear(); inside the function and return the variable year. 

function getYear(){
  var year = new Date().getFullYear();  //this adds the requested line
return year; //this returns the year variable
}

Step three call the getYear function and store the returned value in a variable called yearToday. 

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

var yearToday = getYear(); //this creates a variable named yearToday and sets it equal to the value returned from calling (also known as invoking) the function getYear. You call (or invoke) a function in javascript by putting the function name followed by an open in closed parenthese () for example: getYear()

It wants you to put the return in the function so that when you call the function it will actually return the year. Without the return in the function it wouldn't really do anything other than store the variable year.

function getYear() {
    //store a variable that will get the year
    var year = newDate().getFullYear();
    //return that variable when the function is called
    return year
}
