My Solution for this challenge...

/dice.js folder/

function dice(sides) { this.sides = 6; this.roll = Math.floor(Math.random() * this.sides) + 1; return this.roll; }

var Dice = new dice();

/*** ui.js folder ***/

function printNumber(number) { var placeholder = document.getElementById("placeholder"); placeholder.innerHTML = number; }

var button = document.getElementById("button");

button.onclick = function() { var result = dice(); printNumber(result); };

Hey there Kevin, not sure if you are looking for feedback here but without making use of the parameter javascript this.sides = sides; your dice can only ever roll within 1-6, even if you run it as javascript dice10 = new dice(10); as it is hard coded to only have javascript this.sides = 6;. Let me know if you have any questions, happy learning!

function dice(sides) {
   this.sides = sides; 
   this.roll = Math.floor(Math.random() * this.sides) + 1; 
   return this.roll;

Hi Thomas,

You make a great point thank you. I had been playing around with alternative methods to make the challenge work, although i did not realize my solution is now hard coded to max 6. Thank you for the constructive feedback! :)
