# symbol? Where and when was this symbol covered?

What video do I need to watch to understand what the # symbol does. I dont remember Dave going over it at all

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

var userName = id.toUpperCase();
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Hi Sean,

The '#' is not a special javascript symbol. It is a string character, just like any other letter. The challenge wants you to concatenate a string and part of that string will be a '#' symbol.

Good luck.

I should add though, that the '#' is important in HTML and CSS when selecting id attributes, and if you are using jQuery, for example, you are able to target them with javascript. So in that case the '#' symbol will present itself as a special symbol in javascript, but only because of the relation to the id attributes.
