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

I still can't figure out this challenge

In this challenge I am supposed to use the JavaScript .toUpperCase() to assign an uppercase id variable to the userName variable. However, when I do this I get a message saying "Bummer! The 'userName' variable is '(insert uppercase id, I can't remember it off the top of my head)', not (insert uppercase id) #SMITH" I suspect that there is something wrong with this challenge as I have already done concatination and am currently on functions, but if I am doing something wrong, what should I do to fix it?

Thanks, Ben Esther

app.js
var id = "23188xtr";
var lastName = "Smith";
id.toUpperCase();
var userName = id;

Don't forget to store the result in the variable.

Most methods (and certainly the string case conversion ones) don't actually change the thing you call them on. So you need to put the result somewhere.

So this code creates an uppercase version of "id" but then puts the original value of "id" into the new variable:

id.toUpperCase();
var userName = id;

But with a slight rearrangement, the upper case version is put into the new variable instead:

var userName = id.toUpperCase();

```var id = "23188xtr";

var lastName = "Smith";

var userName = id.toUpperCase();

userName += '#' + lastName.toUpperCase;```

Thanks for your help. However, when I enter this code for the 2nd part of the challenge it says 'Oops! It looks like step 1 is no longer passing!''

It looks like you forgot the parentheses in your second call to toUpperCase().
