Algorithm 101: 2 Ways to FizzBuzz a Range of Numbers

#algorithms #javascript #beginners #fizzbuzz

In the last article, we looked at how we can fizzBuzz a signle number. This article is taking us further to how we can fizzBuzz a range of number. It is going to however, depend upon the function from the last article - 4 Ways to FizzBuzz a Single Number.

fizzBuzzRange([1, 9]) 
/* 
  1
  2
  Fizz
  4
  Buzz
  Fizz
  7
  8
  Fizz
*/
fizzBuzzRange([30, 25])
/*
  FizzBuzz
  29
  28
  Fizz
  26
  Buzz
*/

Are you already thinking it out? I will be showing you 2 ways to do this both for a descending range (example: from 9 to 1) and ascending range (example: from 1 to 9)

Prerequisite

To benefit from this article, you need to check out the preceding article and possess basic understanding of javascript's array methods.

Let's FizzBuzz a Range of Numbers Using:

if...statement and for...loop

      function fizzBuzzRange(array) {
        if (array[0] < array[1]) {
          for (let i = array[0]; i <= array[1]; i++) {
            console.log(fizzBuzz(i));
          }
        }

        if (array[0] > array[1]) {
          for (let i = array[0]; i >= array[1]; i--) {
            console.log(fizzBuzz(i));
          }
        }
      }

switch...statement and while...loop

      function fizzBuzzRange(array) {
        switch (array[0] < array[1]) {
          case true:
            counter = array[0];
            while (counter <= array[1]) {
              console.log(fizzBuzz(counter));
              counter++;
            }
            break;

          case false:
            counter = array[0];
            while (counter >= array[1]) {
              console.log(fizzBuzz(counter));
              counter--;
            }
            break;
        }
      }
