Is there something wrong with my code?

Question

I tried to make a JS program that was supposed to output all the numbers from 1 to 100 but all the numbers dividable by 3 was supposed to output "Fizz" and every number dividable by 5 should say "Buzz. Here it is:
for(var i = 0; i <= 100; i++) {
if(i%=3==0) {
document.write("Fizz \n");
}
else if(i%=5==0) {
document.write("Buzz \n");
}
else {
document.write(i+"\n");
}
}
Can you help me?

Answer 1

You don't test all your cases:

You need to test if dividable by 3 and by 5... but also if dividable by 3 and 5: actually, in this case, you output "Fizz" but not "Buzz" for multiplier of 15 ( 3*5 )... Add a test at start of your if-else chain to fix that... And you must not use the %= operator in your test condition, as it's an assignement operator, so value of i was changed ( you don't compare the good value on next comparisons, in addtion to do an infinite loop -- i was always lighter than 3 ):

for(var i = 0; i <= 100; i++) {
if(i%3==0)&&(i%5==0) {
document.write("Fizz'n'Buzz<br>");
}
else if(i%3==0) {
document.write("Fizz<br>");
}
else if(i%5==0) {
document.write("Buzz<br>");
}
else {
document.write(i+"<br>");
}
}

I've changed you '\n' by '<br>', as usually you are output in Html document ( so default behavior is to ignore break-lines chars )...

Answer 2

if(i%=5==0)

Answer 3

that doesnt change anything, "else if" allows you to add another comparison just like an "if" statement does

Answer 4

i mean u need to delete the = operator before the 5
