Intruduction to Programming (EXTRA for Loops)

Good day! I was trying to achieve the EXTRA thingie at the INTRODUCTION TO PROGRAMMING - Control Structures.

I was setting this code in the console:

for ( var i = 0; i <= 100; i++) {
        if( i % 3 == 0) {console.log("Fizz");}
        else if( i % 5 == 0) {console.log("Buzz");}
                else if( i % 3 == 0 && i % 5 == 0) {console.log("FizzBuzz!");}
        else {
            console.log(i);
        }
}

But it didnt work. I went for a stupid solution such as:

for ( var i = 0; i <= 100; i++) {


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

Any ideas on why the AND isnt working over there? :\

It looks like your condition is in the wrong place. If you place the AND statement as the first condition and the other conditions lead off that, then it will work.

Take 15. Reading your code. Am I divisible by 3? Yes - Execute "Fizz". That's it - it met a condition and the other statements are ignored. So change your code too

for ( var i = 0; i <= 100; 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);
        }

That should work. Hope this helps.

I don't even know how much dumb can I be for not thinking in such a way. The teacher's right, we have to think like computers, not like humans. Dammit. Thank you man!
