Tell us what’s happening:

Hi all,

The code below is not passing the tutorial and keeps saying
You should use the return keyword.

Could anyone please give me more hints?

Your code so far

const median = nums => {
    const sorted = nums.slice().sort((a, b) => a - b);
    const length = sorted.length;
    const middle = Math.ceil(length / 2 - 1);
    return isEven(length) ?(sorted[middle] + sorted[middle + 1]) / 2 : sorted[middle];
};

Hey @twghydc4b01
This is what is missing in your code

you’ll need to round the middle value up.

3

yup. Math.ceil() was used

4

Now add it in the last bit of the fuction of your tenary operator here

Remove it here

5

interesting, after moving the Math.ceil like this sorted[Math.ceil(middle)]
finally another hints other than using return is pop out

If the ternary is truthy, you should call your average() function.

and the code below got pass, many thanks @opudoprince
