--description--

Write a generalized version of FizzBuzz that works for any list of factors, along with their words.

This is basically a "fizzbuzz" implementation where the rules of the game are supplied to the user. Create a function to implement this. The function should take two parameters.

The first will be an array with the FizzBuzz rules. For example: [ [3, "Fizz"] , [5, "Buzz"] ].

This indicates that Fizz should be printed if the number is a multiple of 3 and Buzz if it is a multiple of 5. If it is a multiple of both then the strings should be concatenated in the order specified in the array. In this case, FizzBuzz if the number is a multiple of 3 and 5.

The second parameter is the number for which the function should return a string as stated above.

--hints--

genFizzBuzz should be a function.

assert(typeof genFizzBuzz == 'function');

genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 6) should return a string.

assert(
  typeof genFizzBuzz(
    [
      [3, 'Fizz'],
      [5, 'Buzz']
    ],
    6
  ) == 'string'
);

genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 6) should return "Fizz".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Fizz'],
      [5, 'Buzz']
    ],
    6
  ),
  'Fizz'
);

genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 10) should return "Buzz".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Fizz'],
      [5, 'Buzz']
    ],
    10
  ),
  'Buzz'
);

genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 12) should return "Buzz".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Buzz'],
      [5, 'Fizz']
    ],
    12
  ),
  'Buzz'
);

genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 13) should return "13".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Buzz'],
      [5, 'Fizz']
    ],
    13
  ),
  '13'
);

genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 15) should return "BuzzFizz".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Buzz'],
      [5, 'Fizz']
    ],
    15
  ),
  'BuzzFizz'
);

genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 15) should return "FizzBuzz".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Fizz'],
      [5, 'Buzz']
    ],
    15
  ),
  'FizzBuzz'
);

genFizzBuzz([[3, "Fizz"],[5, "Buzz"],[7, "Baxx"]], 105) should return "FizzBuzzBaxx".

assert.equal(
  genFizzBuzz(
    [
      [3, 'Fizz'],
      [5, 'Buzz'],
      [7, 'Baxx']
    ],
    105
  ),
  'FizzBuzzBaxx'
);

  let res='';

    if(num % e[0] == 0)
      res+=e[1];
