--- id: 5a23c84252665b21eecc7e78 title: General FizzBuzz challengeType: 5 forumTopicId: 302273 dashedName: general-fizzbuzz --- # --description-- Write a generalized version of [FizzBuzz](https://rosettacode.org/wiki/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. ```js assert(typeof genFizzBuzz == 'function'); ``` `genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 6)` should return a string. ```js assert( typeof genFizzBuzz( [ [3, 'Fizz'], [5, 'Buzz'] ], 6 ) == 'string' ); ``` `genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 6)` should return `"Fizz"`. ```js assert.equal( genFizzBuzz( [ [3, 'Fizz'], [5, 'Buzz'] ], 6 ), 'Fizz' ); ``` `genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 10)` should return `"Buzz"`. ```js assert.equal( genFizzBuzz( [ [3, 'Fizz'], [5, 'Buzz'] ], 10 ), 'Buzz' ); ``` `genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 12)` should return `"Buzz"`. ```js assert.equal( genFizzBuzz( [ [3, 'Buzz'], [5, 'Fizz'] ], 12 ), 'Buzz' ); ``` `genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 13)` should return `"13"`. ```js assert.equal( genFizzBuzz( [ [3, 'Buzz'], [5, 'Fizz'] ], 13 ), '13' ); ``` `genFizzBuzz([[3, "Buzz"],[5, "Fizz"]], 15)` should return `"BuzzFizz"`. ```js assert.equal( genFizzBuzz( [ [3, 'Buzz'], [5, 'Fizz'] ], 15 ), 'BuzzFizz' ); ``` `genFizzBuzz([[3, "Fizz"],[5, "Buzz"]], 15)` should return `"FizzBuzz"`. ```js assert.equal( genFizzBuzz( [ [3, 'Fizz'], [5, 'Buzz'] ], 15 ), 'FizzBuzz' ); ``` `genFizzBuzz([[3, "Fizz"],[5, "Buzz"],[7, "Baxx"]], 105)` should return `"FizzBuzzBaxx"`. ```js assert.equal( genFizzBuzz( [ [3, 'Fizz'], [5, 'Buzz'], [7, 'Baxx'] ], 105 ), 'FizzBuzzBaxx' ); ``` # --seed-- ## --seed-contents-- ```js function genFizzBuzz(rules, num) { } ``` # --solutions-- ```js function genFizzBuzz(rules, num) { let res=''; rules.forEach(function (e) { if(num % e[0] == 0) res+=e[1]; }) if(res==''){ res=num.toString(); } return res; } ```
