Challenge: Understanding Uninitialized Variables

Link to the challenge:

Hi and welcome,

You initialized those variable after the operations, which you are not supposed to do. If you console-logged those variable it will return:

6
15
I am a!

Instead of result of these operations:

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

In addition to advice above:
you have a typo
I am a
and
I am a!
are not the same

Thanks a lot, i appreciate.
