Javascript while Statement Question 4

Introduction

Statistics to Doubles

Implement a 'die' that randomly returns an integer between 1 and 6 inclusive.

Roll a pair of these dice, tracking the statistics until doubles are rolled.

Display the number of rolls, min, max, and average. 

function die(){// w w  w . j  a  va  2s . c o  m
  var count = 0;
  var sum = 0;
  var min;
  var max;
  var avg;
  //your code
  result = ["rolls: " + count, "minimum: " + min, "maximum: " + max, "average: " + avg];
  return result;
}
console.log(die());
 



function die(){
  var count = 0;
  var sum = 0;
  var min;
  var max;
  var avg;
  do {
    var roll_1 = Math.floor((Math.random() * 6)+1);
    var roll_2 = Math.floor((Math.random() * 6)+1);

    console.log(roll_1, roll_2);
    count++;
    sum += roll_1 + roll_2;

    if (min == undefined) {
      min = roll_1 + roll_2;
    }
    else if (roll_1 + roll_2 < min) {
      min = roll_1 + roll_2;
    }

    if (max == undefined) {
      max = roll_1 + roll_2;
    }
    else if (roll_1 + roll_2 > max) {
      max= roll_1 + roll_2;
    }

  } while(roll_1 != roll_2)


  avg = (sum / count).toFixed(1);
  result = ["rolls: " + count, "minimum: " + min, "maximum: " + max, "average: " + avg];

  return result;
}
console.log(die());
