Ok it says return but it is not outputting anywhere, no alert, console or document.write.

Regarding this question, the function is called but is nothing going to happen? Seeing as though the code is not being asked to be displayed in a console , screen or alert?

Hey Yacine, it didn't show the exact question you were asking about, was this it?

function getDay() {
  return "Monday";
  alert("Calculating day");
  return "Friday";
}

var dayOfWeek = getDay();

If so, you are correct, there is no output to the DOM or console coming from this function. This snippet of JavaScript is simply returning the value "Monday" when the getDay() function runs. This value is then set as the var dayOfWeek. This is still a functional piece of code without any console or HTML output, and often 100's of lines of code can be run behind the scenes of a webpage without specifically outputting the to DOM. It is part of what makes JavaScript so versatile.

Hope this helps!
