FizzzBuzzz Problem PLS help

[Pendejo]

Hallo, could someone help me pls?

I try to solve the FizzBuzz task.
FizzBuzz
Write a program that uses console.log to print all the numbers from 1 to 100,
with two exceptions. For numbers divisible by 3, print “Fizz” instead of the
number, and for numbers divisible by 5 (and not 3), print “Buzz” instead.
When you have that working, modify your program to print “FizzBuzz” for
numbers that are divisible by both 3 and 5 (and still print “Fizz” or “Buzz”
for numbers divisible by only one of those).
(This is actually an interview question that has been claimed to weed out
a significant percentage of programmer candidates. So if you solved it, your
labor market value just went up.)

I understand the solution but i have some problems witch i underlined with red color at the screenshot.

i % 3 == 0

1. why is it “0”? It should be not " 0 " but some kind of term for a “whole number/integer” and not zero “0” in my opinion. (3 divided by 3 is 1 and not 0 “zero” i would say:))

else if(i % 5 == 0 && i % 3 !=0)

2. what i dont realy understand is why its two times “=” equal sign and only one time “=” equal sine at the end (!=0).

Can someone pls help me and explain me in easy english?
Thx, and sorry for my not perfect english.

Hi Pendejo,

Don’t worry your English is great. Hopefully, I can answer this clearly:

% is called modulus which is the remainder of a division not the division itself:
e.g. 3 / 3 (3 divided by 3) is 1
e.g. 3 % 3 (what is the remainder of 3 divided by 3) is 0
Here’s a good reference of operators and math:
https://www.w3schools.com/js/js_operators.asp
https://www.w3schools.com/js/js_arithmetic.asp

A single operator (above) is used to change or assign variables:
// creates a variable called ‘name’ and assign it a (string/text)value of ‘Pendejo’
e.g. name = “Pendejo”;
// creates a variable called ‘ageNextYear’ and assigns it a value of the age variable plus 1
e.g. ageNextYear = age + 1;

A double operator is used to compare or check something:
e.g. if (name == “Pendejo”) {
console.log(“Hello Pendejo)”;
}
else
console.log(“Who the hell are you?”);
…

Ivan’s course is absolutely fantastic but I think for people who are either new or a little rusty to coding, like I was, I’d suggest going through this free course: https://www.codecademy.com/learn/introduction-to-javascript

Hope that helps and feel free to ask anything else.

Let’s start by learning about the JavaScript operators. Operators in JavaScript are used to perform operations over any data. Or operators are indications between those values, which allow for different operations such as extra, subtraction, multiplication, and more.

Javascript operators have some special types of symbols or symbols. Which are often represented by mathematical symbols. Such as * multiplication, division,% modulus, lecturer etc. Friends JavaScript operators reflect the implementation of a process.
