Tell us what’s happening:

const getHighestDuplicates = (arr) => {
let countObj = {}
let totalScore = 0;
let maxCount = 0;
let maxDuplicate = null;
arr.forEach((num) => {
countObj[num] = (countObj[num] || 0) + 1;
totalScore += num;
});
if (countObj[num] > maxCount) {
maxCount = countObj[num]; // value
maxDuplicate = num // key
}

if (maxCount < 3) {
updateRadioOption(5, 0)
} else if (maxCount === 3) {
updateRadioOption(0, totalScore)
} else if (maxCount === 4) {
updateRad

Hi did you have any questions about the code or instructions?

3

they tell me in the console “num” it’s not defind

4

Sounds like a very good clue. How can you use this?

Can you find in your code where the num variable is set?

5

in forEach !
should i put if statement inside the forEach ?

6

Makes sense.

num is defined only within the forEach. Outside of that method it’s not accessible.
