Hi Jawad! You are on the right track! Your first two steps are spot on: var firstName = "Jawad"; var lastName = "Wahedi";

Once we get to task 3, it's asking us to combine the info stored in the first two variables into a new variable. To combine, we just need to use the "+"

ex. var example = variable1 + variable2;

Hope this helps!

Hi Mike Thank you for the answer. actually i tried this: var firstName = "jawad"; var lastName = "Jawad"; var fullName = "hello"; fullName += "Jawad Wahedi";

and it worked but honestly i didnt get it, how it worked?

Hi Jawad,

Yes! It looks like that will work as well. Here's why I think it works too

You created a 3rd variable, var fullName = "hello".

Currently, the only thing stored in this variable is the string "hello

then, you use "+=" which takes whatever is currently stored in fullName, in this case 'hello", and adds the string 'Jawad Wahedi'.

now, fullName should have this: "hello Jawad Wahedi".

This gives us a similar result of : var fullName = firstName + lastName; In this case, we are just adding together whatever strings are stored in firstName and lastName, which are just "Jawad" & "Wahedi".

At least that is what I think is happening. Hope this helped and hasn't added to any confusion. Looks like two different approaches for a similar result.

All the best!
