/*for (var i =1 ; i < 21 ; i++){
    if (i%3===0){
        if (i%5===0){
            console.log("FizzBuzz");
        } else {
            console.log("Fizz");
        }

            console.log("Buzz");
    }
};*/

What's wrong? 


It shows in console ,that everything right, but even says that it's wrong


What is wrong here
Not printing FizzBuzz

@corerunner69561,

+++++++++++++++++ for loop wrong FIZZ BUZZ condition in DIAGRAM
Javascript has the so-called Remainder-operator %
is actually a modulo-operator
and if used it will return the rest-value.

9%3 You read it as nine modulo three is zero, as 9 divided by 3 has NO rest-value.
22%6 You read 22 modulo six is 4, as 22 divided by 6 will leave you with rest-value 4
10%5 You read 10 nodulo five is zero, as 10 divided by 5 will have NO rest-value

In this section you have to figure out
(i%3 === 0 && i%5 === 0) to display FizzBuzz // if (imodulo 3 equals zero AND imodulo 5 equals zero)
(i%3 === 0) to display Fizz // else if (i modulo 3 equals zero )
(i%5 === 0) to display Buzz // else if (i modulo 5 equals zero )
AND
if none of the above display i //else display i

You will have to use an IF ELSE-IF ELSE-IF ELSE-statement
within a for-loop.

Oh, thanks. Before i made it the same way, but the condition for "FizzBuzz" stand in the end.
I've tried 3 different way, how it could work.

And thank you very much for links!!!
