Do not change code below this line

Your code so far


// Initialize these three variables
var a;
var b;
var c;

// Do not change code below this line

a = 5 + 1;
b = 10 + 5;
c = "I am a String!";

It means, the only lines of code you should be changing for this lesson are the following lines:

var a;
var b;
var c;

The code below the // Do not change code below this line is necessary for the tests that run once you submit. The exercise is asking you to initialize the the variables you can do that immediately after they are declared. In other words you can either assign a value to the variable when it created or right after it is declared. See https://www.w3schools.com/jsref/jsref_var.asp

var a;
a = 5;

or

var a = 5;

So you don’t need to change any thing below the comment you mentioned on line #6, happy coding!

The above would not really be considered initialization. Initialization is when the declaration and the assignment happen at the same time (in this case it would be var a = 5;.
