How did you figure out this one?

Hi could you lend me a hand with this one?

Kudos!

Challenge Task 2 of 2

Finally, add a # symbol and lastName in uppercase to the end of the userName string. The final value of userName is "23188XTR#SMITH".

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

var userName = id.toUpperCase();
username += lastName.toUpperCase();

Hi! Your id is good. Combine the two included # without space character. Like this:

userName = userName+'#'+lastName.toUpperCase();

Looks like Adam beat me to it. Also, the video before that discusses combining strings.

Also, instead of watching the whole video, you can look at the teacher's notes to get that info quickly.

Variable names in Javascript are case sensitive. Change: username += lastName.toUpperCase(); TO: userName += lastName.toUpperCase();
