You've got much of it there, the assignment operator (=) causes what you put on the right side to be stored in what's on the left. And "var" creates a new variable. But since you would not normally call a function that returns something by itself, I'm guessing what you wanted to store was the result of the function (which would not be associated with the word "result" unless you create a variable with that name and assign it).

So with a slight rearrangement you'd have this:

var yearToday = getYear();
