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

the problem is that the task is asking me to use toUpperCase on "lastName", but the solution tips tells me that is wrong

the problem is that the task is asking me to use toUpperCase on "lastName", but the solution tips tells me that is wrong. I'm having a hard time figuring this out.

TASK: 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".

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

It tells me that it is wrong! -.-!

David is correct. It is only making a seperate instance of id rather then setting it as the variables value. there are a few ways to answer this challenge. if you were to follow your current code. then I would try this.

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

I hope this helps.

It first asks you to assign the an Upper case value of id to username.

This line

id.toUpperCase();

does not set the an Uppercase version of id to username.

The .toUpperCase(); method returns a string back IT DOES NOT SET id to an upper case string;

You need to set username to an uppercase version of id then set username to it's current value + the "#" + uppercase version of lastName.

Thanks Guys!
