how do you do that

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

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

var userName = id.toUpperCase();
index.html 
<!DOCTYPE HTML>

Hi,

you need to use + operator to concatenate strings or concat function, so: you already have 

var id = "23188xtr";

if you do something like

var idUpperCased = id.toUpperCase()

you will get "23188XTR", as expected.

Later you're asked to add hash, so you use + operator, so I could do this using my previous variable:

var someVariable = idUpperCased + "#"

or alltogether:

var someVariable = id.toUpperCase() + "#"

add the end you also need to add uppercased name to finish task. Also variable it all should be hold in is userName, so:

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

Please refere to code below:

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

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

I hope it helps :)

Cheers!

That's another way than what I was suggesting, but it also works.

You can connect strings together using concatenation.

The concatenation operator is the plus sign ("+"). So for example, if you wanted to add the contents of a variable to a literal string:

name = "Kal-El";
greeting = "Hello, my name is " + name;  // <- string concatenation

You can also do a concatenation assignment ("+=") to add on to an existing string. That might come in handy for that last task.

I'll bet you can get it now without an explicit spoiler.

Hi Shihab, with code I provided at the end of my previous post, both tasks are passing ok.

Maybe you should check it with different browser?

Let me know if you still have a problem!

I'd need to see what the script code looks like after you modified it. If you show it here I will take another look.
