Tell us what’s happening:

Grand Rising to everyone;

I am having some problem setting up this code to meet up with the requirements in the task. I have used the forEach() and the current for…in loop to complete the task , but I keep ending up with the same message as shown below:

When the array has three of the same number, your getHighestDuplicates function should update the Three of a Kind radio option with , score = and the total sum of the dice.

I have spend some hours figuring this out on my own but at this point, I find it connivence to seek external help. Can someone please me point out the fault in the blocks of code below. Your kind gestures will be much appreciated.

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

const getHighestDuplicates = (array) => {
  let counts = [];
  let fourOfAKind = "disabled";
  let threeOfAKind = "disabled";

  for (const dice in array) {
    if (counts[dice]) {
      counts[dice]++;
    } else {
      counts[dice];
    }
  }

  let identicalNum = 0;

  for (const dice in array) {
    const getCount = counts[dice];
    if(getCount >= 4 && getCount > identicalNum) {
      identicalNum = getCount;
    } else if(getCount >= 3 && getCount > identicalNum) {
      identicalNum = getCount;
    }
  }

  const sumAllDice = array.reduce((ax, az) => az + az, 0);

  if (identicalNum >= 4) {
    fourOfAKind = "enabled";
    updateRadioOption(1, sumAllDice);
  } else if (identicalNum >= 3) {
    threeOfAKind = "enabled";
    updateRadioOption(0, sumAllDice);
  } else {
    fourOfAKind;
    threeOfAKind;
    updateRadioOption(5, 0);
  }
};

Hi there!

you should correctly increment counts[dice], and counts should be an object, not an array, to handle the dice value as key.

The logic in the second loop seems incorrect; it could miss some counts due to comparing and assigning identicalNum.

The reduce function is incorrectly summing values as az + az instead of ax + az.

Thanks for the hint! I have been wresting with the code for some minutes now. I am going to ratify the error now and to a little more touching.
