Uninitialized Variables

JavaScript
1

Tell us what’s happening:

Please, any help me???

Your code so far

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

// Do not change code below this line

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

//

var a = 5;
var b = 10;
var c = " I am a";

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

In the results, I get this:
X = fail/error

ok - a should be defined and have a value of 6
ok - b should be defined and have a value of 15
X - c should not contain undefined and should have a value of “I am a String!”
ok - Do not change code below the line
