Help with the c string

Tell us what’s happening:
Describe your issue in detail here.

Your code so far

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

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

Challenge: Understanding Uninitialized Variables

Link to the challenge:

The error message you are getting is a little confusing because it states that c should not contain undefined which doesn’t make sense here and is probably a bug in the test. The second part of the error message is correct though:

"should have a value of the string I am a String!"

Notice in your code you have added a space before the “I”. Is there a reason you added that, or is it just a mistake? These tests can be very picky about such things and your solution usually needs to be exactly the same as what the instructions are asking.
