Greetings! I do not understand why I have to describe that variable " ". http://www.w3schools.com/js/tryit.asp?filename=tryjs_loop_for_ex When I put a letter in it, it returns "aThe number is 0 (...)" only the first character, not every loop. So why we need to describe empty value. Why we want to write there nothing ->
