# Getting an error for FizzBuzz exercise

#1

I'm trying to figure out the code for the problem it says "Oops, try again. It looks like you printed out the wrong number of items"

var okdude = function(){
for(var i=1; i <= 20; i++){

if(i%3 != 0 && i%5 != 0){
console.log(i);
}

else{

if(i%3 != 0 && i%5 != 0){
console.log("FizzBuzz");
}
else if(i%3===0){
console.log("Fizz");
}
else if(i%5===0){
console.log("Buzz");
}
else {
console.log(i);
}
}
}

}

Not necessary. That condition is the default in the else statement at the end.

This conditional needs to check identity:

if (i % 3 === 0 && i % 5 === 0) {
console.log("FizzBuzz");
}

+++++++++ modulo ++ FizzBuzz ++++++++++++++++
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.

I still get same error:

var okdude = function(){
for(var i=1; i <= 20; i++){

if(i%3 === 0 && i%5 === 0){
console.log("FizzBuzz");
}
else if(i%3===0){
console.log("Fizz");
}
else if(i%5===0){
console.log("Buzz");
}
else {
console.log(i);
}

}

}

#5
for(var i=1; i<21;i++) {

if(i%3 === 0 && i%5 === 0){
console.log("FizzBuzz");
}
else if(i%3===0){
console.log("Fizz");
}
else if(i%5===0){
console.log("Buzz");
}
else {
console.log(i);
}
}

you dont need to so that function stuff, just do the for loop

that worked - appreciate it!
