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

i literally spent 1 hour trying to figure this out

var id = "23188xtr"; var lastName = "Smith"; id.toUpperCase(); var userName lastName.toUpperCase(); userName = (id + "#" + lastName);

the code only outputs lower case letters besides the S. i need to make sure that the username outputs all in cap letters and with # in the middle of the id and last name. what am i doing wrong?

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

The line above "lastname.toUpperCase()" is missing a semi-colon. Otherwise your code looks good.

i think im doing it correctly but it literally keeps telling me this

Bummer! The userName variable is "23188xtr#Smith" not "23188XTR#SMITH".

I got it to work by using: id=id.toUpperCase(); and lastName=lastName.toUpperCase();

I think I used the method when I put the string together: userName = (id.toUpperCase() + "#" + lastName.toUpperCase()); It looks like you have to put it back into the variable with the "=" if you do it in a separate step.

Bummer! The userName variable is "23188XTR#SMITH" not "23188XTR#SMITH".

lol this is weird. do i have to put uppercase method after i already declared the new value? thanks for answering!

That error message makes no sense at all!

It looks like you have both id.toUpperCase(); AND id=id.toUpperCase(); (same with the last name...)

Get rid of the extra lines (the two without "=") and see how the program likes it then...

No, it happens all the time, and to everyone once in a while. The more mistakes you make, the more you learn. I wouldn't be able to help if I hadn't made the same mistakes myself.
