The directions below confuse me. Where is the end of the string?

(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('#lastName') + #lastname;

Hi Joshua,

You're are on the right track by assigning the string method .toUpperCase to id. You also should pass the lastName variable as a parameter for the string method.

This way you are assigning an all uppercase version of the id variable to the userName variable.

var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase(lastName)

One way to add the '#' symbol in between the id and lastName is to separate the two:

var id = "23188xtr";
var lastName = "Smith";

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

Another way is to use template literals:

var userName = `${id.toUpperCase()}#${lastName.toUpperCase()}`;
