Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName v

Hi! I am working on this code and I am having trouble understanding what it is I am going to fix. I don´t understand the question. Please help.

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

var userName = 'id'+'lastName'): console.log('id'.toUpperCase());

<!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>JavaScript Basics</title> </head> <body> <script src="app.js"></script> </body> </html>

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

var userName = 'id'+'lastName'):
console.log('id'.toUpperCase());

Louise,

Remember, the instruction is to 'use the .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName variable'.

When I read that, I see two steps:

  1. Use the string method to make id uppercase, and
  2. Assign that uppercased variable to userName. (Hint: you've done this in the console.log statement, but you don't need to use console log--because you're not being asked to output anything.)

For step 1 of the Challenge, you can do both steps in one line of code.

For step 2 of the Challenge, you add (concatenate with the '+' symbol) the "#" and lastName variable to the end of that line of code.

Here's a few hints:

  • you won't need "console.log" in this challenge
  • only what you assign to "userName" will be checked
  • there's a stray closing parenthesis on the line where "userName" is assigned
