In Javascript basics, I'm being asked to call the getYear function and store the returned value in a variable called yearToday. I've tried several things and it just isn't working. I'm hoping my code is attached to this post.
function getYear() {
var year = new Date().getFullYear();
return year;
}
getyear();

You're nearly there, just need to store the return value in a variable called "yearToday":
function getYear() {
var year = new Date().getFullYear();
return year;
}
var yearToday = getYear();

231,248 PointsYou've got the "calling" part right.
When you call a function, you put parentheses after the name. So you got that part.
So when you store something in a variable, you perform an assignment operation. The assignment symbol is equal sign ("="). What you are assigning (the function call) goes on the right side. Where you are putting it (the variable) goes on the left side. Then all you need is the keyword "var" in front of the variable name to show that it is being created.
I'll bet you can get it now without an explicit spoiler.

<script>document.write(new Date().getFullYear())</script>

7,310 PointsHey this is what I got for ya; I want to say you don't need the semicolon when you return a value..semicolons in JS are a huge headache because sometimes you randomly don't need them and also you just forgot to store the var... so close!!! Good luck :)
function getYear(){ var year = new Date().getFullYear(); return year
};
