Understanding Uninitialized Variables
Hints
Hint 1
Make sure that the variable has the correct data value. Leaving a variable uninitialized, meaning you do not give it a value, can cause problems if you want to do operations on it.

// 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 = 6;
var b = 15;
var c = “I am a”;
What is wrong with this?
var c should be initialised before it is used since it is a string. try initialising it right after declaration
it should be -
var a = 5;
var b = 10;
var c = “I am a”;
on var c should add ! after String. should be all set!
