What is wrong with my function?

I'm trying to finish this task:

Create a function that calculates the area of a rectangle. The function should accept the width and height as arguments and return the area of that rectangle. The area of a rectangle is the width * height.

My attempt looks like this:

function rectangle() {
   var width = parseInt(prompt("What is the width of this rectangle?"));
   var height = parseInt(prompt("What is the height of this rectangle?"));
   var area = width*height;
   return = area;
}
rectangle();

According to my Console, something is wrong with the code "return = area;" at the end of my function. It says: Uncaught SyntaxError: Unexpected token =

Can someone help me out?

Try "return area;"

Worked, this particular problem is solved - thank you! Unfortunately, something else is not working now. I can't see the value of my variable "area". I added one more line in my function: document.write(area); Do you know what I just did wrong here? :)

Yes, var area is defined within the function so it isn't available.

You could try:

const width = parseInt(prompt("What is the width of this rectangle?"));
const height = parseInt(prompt("What is the height of this rectangle?"));

function rectangle(width, height) {
   return width*height;
}
document.write(rectangle(width, height));
