| // first naive, straight-forward solution: | |
| function divides(a,b) { | |
| return a % b === 0; | |
| } | |
| for (i=1; i<20; i++) { | |
| if (divides(i,3) && divides(i,5)) { | |
| console.log("fizzbuzz"); | |
| } else if (divides(i,3)) { | |
| console.log("fizz"); | |
| } else if (divides(i,5)) { | |
| console.log("buzz"); | |
| } else { | |
| console.log(i); | |
| } | |
| } | |
| // now onto a more functional approach: | |
| function divides(a,b) { | |
| return a % b === 0; | |
| } | |
| function range(n) { | |
| return [...Array(n).keys()]; | |
| } | |
| function fizzbuzz(range, rules) { | |
| return range.map( i => | |
| rules.reduce( (acc, rule) => acc + rule(i), '') || i | |
| ) | |
| } | |
| const rules = [ | |
| x => divides(x, 3) ? 'fizz' : '', | |
| x => divides(x, 5) ? 'buzz' : '' | |
| ] | |
| console.log( fizzbuzz( range(20), rules )); |
