Default parameter not working.

This is my code. When I run it in the console I get the correct calculated number, but units show up as 'undefined' instead of the default 'sq ft'

function getArea(width, length, unit = 'sq ft') { let area = width * length; return ${area} ${unit}; }

getArea(2, 3);

After the return statement you need to use template literals if you want to display all the data. You forgot the `` which signals the start of the template literal

function getArea(width, length, unit = "sq ft") {
  let area = width * length;
  return `${area} ${unit}`;
}
