--description--

Given an integer (n), return an array of integers from 1 to n (inclusive), replacing numbers that are multiple of:

• 3 with "Fizz".
• 5 with "Buzz".
• 3 and 5 with "FizzBuzz".

--hints--

fizzBuzz(2) should return [1, 2].

assert.deepEqual(fizzBuzz(2), [1, 2]);

fizzBuzz(4) should return [1, 2, "Fizz", 4].

assert.deepEqual(fizzBuzz(4), [1, 2, "Fizz", 4]);

fizzBuzz(8) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8].

assert.deepEqual(fizzBuzz(8), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8]);

fizzBuzz(20) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz"].

assert.deepEqual(fizzBuzz(20), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz"]);

fizzBuzz(50) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz", "Fizz", 22, 23, "Fizz", "Buzz", 26, "Fizz", 28, 29, "FizzBuzz", 31, 32, "Fizz", 34, "Buzz", "Fizz", 37, 38, "Fizz", "Buzz", 41, "Fizz", 43, 44, "FizzBuzz", 46, 47, "Fizz", 49, "Buzz"].

assert.deepEqual(fizzBuzz(50), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz", "Fizz", 22, 23, "Fizz", "Buzz", 26, "Fizz", 28, 29, "FizzBuzz", 31, 32, "Fizz", 34, "Buzz", "Fizz", 37, 38, "Fizz", "Buzz", 41, "Fizz", 43, 44, "FizzBuzz", 46, 47, "Fizz", 49, "Buzz"]);
