help me to solve this

Complete the assignment to the userName variable by adding a # symbol followed by an all uppercase version of the lastName variable. In other words, using string concatenation so that the final value of userName is "23188XTR#SMITH".

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

var userName = id.toUpperCase();

Try this:

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

-or- 

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