Basic JavaScript - Understanding Uninitialized Variables

Tell us what’s happening:
The hint is telling me that c should not contain undefined and should have a final value of the string I am a String!. How do I make sure the c does not contain “undefined” ??

Your code so far

// Only change code below this line
var a =5;
var b =10;
var c = "I am a String!";
// Only change code above this line

a = a + 1;
b = b + 5;
c = c + " String!";

Challenge: Basic JavaScript - Understanding Uninitialized Variables

Link to the challenge:

to show you the problem, add this line at the bottom of your code after the line c = c + " String!"

console.log(c);

Then look at the results.
you will see something like

I am a String! String!

Hopefully this will help you understand what you have done incorrectly.
