FizzBuzz solution for values n:m, w/optional divisors & text.
Return an array from values n:m for i, yielding [f] + [b] for value (n+i % div0) === 0 && (n+i % div1) === 0, yielding [f] for value (n+i % div0) === 0, yielding [b] for value (n+i % div1) === 0.
This solution to the FizzBuzz problem was inspired by a thread on Reddit about common frontend developer interview questions. I implemented a solution using a bodyless for-loop with heavy use of ternary operators.
This example was then turned into this Node module for even more concise code during an interview, where the developer can show his/her pragmatism and reluctance for "reinventing the wheel".
Simple usage:
$ npm install -s fizzbuzz.js
Then:
var fizzBuzz = require('fizzbuzz.js').fizzBuzz;
var results = fizzBuzz();
FizzBuzz takes optional arguments:
-
n: (Number) Start value, default:
1 -
m: (Number) End value, defalt:
100 -
f: (String) Alternative Fizz string, default
'Fizz' -
b: (String) Alternative Buzz string, default
'Buzz' -
div0: (Number) Alternative first divisible value, default
3 -
div1: (Number) Alternative second divisible value, default
5
This will return an array for values 1 to 100, for values divisible by 3 and 5.
var fizzBuzz = require('fizzbuzz.js').fizzBuzz;
var results = fizzBuzz(1, 100, 'Fizz', 'Buzz', 3, 5);
Returns an array with the following indexed values:
1 1

3 'Fizz'

5 'Buzz'
6 'Fizz'
7 7
8 8
9 'Fizz'
