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

unknown hash character?

error reads "userName value is '23188XTRSMITH', not '23188XTR#SMITH' ....where did the extra pound/hash sign come from?

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

///variable is "23188xtrSmith" not "23188XTR#SMITH"

Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable.

leave out lastName and try it out.

id + lastName is not necessary, this line is not necessary.

var userName = id.toUpperCase();

The problem here is that you're defining your userName twice. I can copy/paste your code and remove one line and it passes. Just erase this line.

The hash character is used in task 2. Doesn't make much sense in task 1.

yeah, I guess somehow I glitched the website to require the answer for task two during task 1, it seems to have been fixed now.
