Is there anything wrong with doing it this way?

I had the same question. Seems much simpler to me too. :)

I can see why you might want to make your shout a variable for easier use later on in a more complex code, but I don't see why we would ever want to put the exclamation points in a separate line of code, beyond just demonstrating and reinforcing our memory of +=

In the case of wanting the separate variable for shout I would do

var stringToShout = prompt('What do you want to shout?'); var shout = stringToShout.toUpperCase() + "!!!" alert(shout)

Now you can write your shout to the document or log it to console easily, or quickly use it later in your code for whatever other reason, minus the superfluous line of code that was used to reinforce our memory of +=

I used the same 2 line approach but found out that we are using only one variable whereas Dave is creating a new one for future use with uppercase letters. Since it was not asked of us in this video we did not even consider using it and therefore most of us neglected use of 2 variables.
