JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Using String Methods

Posted by Jeremiah Johnson

Is it frustrating on purpose?

I can't figure out the syntax the lesson is looking for. We are supposed to string id and lastName together with a # between the id and lastName and the whole thing is supposed to be in all caps. For some reason no matter how I write it the # is not recognized. What is the trick because I can not figure it out by watching the video or looking through the MDN JavaScript reference page.

app.js 
var id = "23188xtr";
var lastName = "Smith";

var userName = id + "#" + lastName.toUpperCase();
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

You didn't upcase the id

var userName = id.toUpperCase() + "#" + lastName.toUpperCase();

I will try this, I was adding it all in one command then ending it .toUpperCase.

If you want to call the method only once you can do it like so:

var userName = (id + "#" + lastName).toUpperCase();

Hi Jeremiah,

You are supposed to have the id in caps too.

So you need to change your code to:

var userName = id.toUpperCase() + "#" + lastName.toUpperCase();

This is why its giving you an error on the #.

Thank you everyone for all the help! As I get farther on it just keeps getting a little tougher.
