How do i define c to equal "I am a String!"?

Tell us what’s happening:

Your code so far

// Initialize these three variables
var a = 5; // This is equal to 5
var b = 10; // This is equal to 10
var c = "I am a String!"; // This is equal to "I am a String!"

// Do not change code below this line

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

Link to the challenge:

Change the third line of code to c = "I am a" because you want it to concatenate to I am a String!

thank you! i was stuck on that for a while
