Understanding Uninitialized Variables JS

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

Your code so far

// Initialize these three variables
var a = 5;
var b = 10;
var c = "I am a ";

// Do not change code below this line

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

What is wrong here?
ty for answers

Do you have a question?

for var a and for var b i got a corect answer, but i cant figure it out what am i doing wrong on var c line.

It appears you have an extra space character between the words “a” and “String!”

thank you very much. Its woring now
