The # symbol has no significant meaning in Javascript or in this example. It's just an arbitrary string to demonstrate concatenation.

so if i am not put it in the code it will be no demonstrate from concatenation?

yes, It is just there to help you demonstrate concatenation. Remember to set the lastName to use UPPERCASE also before you concatenate it to the userName variable. End result should look like this: userName = id.toUpperCase() + '#' + lastName.toUpperCase();

remember to use ' ' or " " around the # sign because as Benjamin said, it has no special meaning in JS
