Alert not working

Hi so this code was meant to show an alert message saying please enter a name if user doesnt enter a name.But once i dont enter a name it shows the inner html.Could it be that the else statement is wrong https://code.sololearn.com/WZweJ4x3kvHj/?ref=app

<!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <h2 id="Name"> </h2> <script> var Yourname=prompt("what is your name"); if(Yourname){ document.getElementById("Name").innerHTML="hello "+ Yourname; } else{ alert("please enter a name"); } </script> </body> </html>

Because when user enters nothing an empty string is returned. Yourname != null should be: Yourname
