var word = "ID";
var res = word.toUpperCase();
console.log(res)

216,768 PointsIt's not the name "ID" that the challenge is asking you to convert. It's the contents of the id
variable. So you won't need to create "word" or "shout".
Just use the toUppercase()
method directly on the id
variable, and assign the result to userName
.
