Solutions to the Fizzbuzz problem, so far in two languages. Both of them take a user-inputted number and then return the Fizzbuzz solution up until that number.

fizzbuzz.js

$(function () {
	var user_number = prompt('Enter a number!');
	for (var index = 1; index <= user_number; index += 1) {
		if (index % 3 === 0 && index % 5 === 0) {
			document.write('fizzbuzz' + '<br />');
	  } else if (index % 3 === 0) {
			document.write('fizz' + '<br />');
	  } else if (index % 5 === 0) {
			document.write('buzz' + '<br />')
	 } else {
		document.write(index + '<br />');
		}
	}
});

fizzbuzz.rb

def fizzbuzz(number)
	(1..number).each do |i|
		if !(i % 3 == 0) && !(i % 5 == 0)
			puts "#{i}"
		elsif (i % 5 == 0) && (i % 3 == 0)
			puts "FizzBuzz"
		elsif i % 3 == 0
			puts "Fizz"
		else i % 5 == 0
			puts "Buzz"
		end
	end
end
