Basic JavaScript - Understanding Uninitialized Variables

Tell us what’s happening:
Describe your issue in detail here.
I’m getting these 2 errors, i’m not sure what is wrong with the code. It makes sense when i read.

  • Failed:a should be defined and have a final value of 6.
  • Failed:b should be defined and have a final value of 15.

Your code so far

// Only change the code below this line
var a =6;
var b =15;
var c = "I am a";
// 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:

The final value should be 6 and 15, not the initial value.

Here the initial value is updated.

Initialize the three variables a, b, and c with 5, 10, and “I am a” respectively so that they will not be undefined.
