Lucky Fizz Buzz Coding Challenge

Part 1 Fizz Buzz

Write a program that prints the numbers from 1 to 100.

  • But for multiples of three print “Fizz” instead of the number
  • And for the multiples of five print “Buzz”.
  • For numbers which are multiples of both three and five print “FizzBuzz”.

Tests have been written to guide you:

npm t

  • Uncomment the tests one at a time
  • Run the tests and watch them fail
  • Implement the code in fizzbuzz.js to make the tests pass
  • Repeat until all tests pass

Part 2 Lucky Fizz Buzz

The business owners have decided that any number with a 3 in it should now return "lucky" for example: 3, 13, 23, 37

Hints

Remainder (%) The remainder operator (%) returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.

console.log(12 % 5);
// expected output: 2

console.log(4 % 2);
// expected output: 0

console.log(12 % 4);
// expected output: 0

Note that while in most languages, ‘%’ is a remainder operator, in some (e.g. Python, Perl) it is a modulo operator. For positive values, the two are equivalent, but when the dividend and divisor are of different signs, they give different results. To obtain a modulo in JavaScript, in place of a % n, use ((a % n ) + n ) % n.
