JavaScript The Solution

The alert doesn't work.

The alert in my code doesn't work. Everything works fine until I add the alert - then nothing works and the console says that it's a SyntaxError with missing ) on that line. It was first identical with Dave's solution in the video and didn't work. After reading the other questions and answers here I added a " after "is" but it still doesn't work. Would be glad for some help!

let firstName = prompt("What is your first name?", "Write your first name here");

let familyName = prompt("What is your family name?", "Write your family name here");

let completeName = firstName.toUpperCase() + ' ' + familyName.toUpperCase();

let characterCount = completeName.length;

alert("The String \"" + completeName + "\" is " + " characterCount + " characters long.");

alert(The String ${completeName} is ${characterCount} characters long.);

Hi Ingrid. You forgot to add the backticks here ``

Hey Ingrid Pettersson,

The reason for that syntax error is because your last ) is being treated as if it were part of a string (and not the closing parenthesis for the alert function). I think you may have gotten a bit confused with all of the double quotes and concatenating in that alert function.

My advice would be to re-start the entire string with single quotes, that way you won’t have to escape your double quotes. If you do this, I think you’ll see where you’ve opened a string without ending it.

I tried that but still couldn't find the error. Now I learned that the new JavaScript syntax for this alert would be as follows:

alert(The String ${completeName} is ${characterCount} characters long.);

When I do this it works! Would you say that this is the same function but with newer JS syntax, or is there a difference between the functions?

Thank you Brandon!
