Tell us what’s happening:

sum,
average,
median,
even: nums => nums.filter(isEven),
someeven: nums => nums.some(isEven),
everyeven: nums => nums.every(isEven),
firsttwo: nums => nums.slice(0, 2),
lasttwo: nums => nums.slice(-2),
has2: nums => nums.includes(2),
increment: nums => nums.map(num => num + 1),
random: ([x, y]) => Math.floor(Math.random() * y + x),
range: nums => range(…nums),
nodupes: nums => […new Set(nums).values()]
“” : () => (“”),
}

not sure what is wrong.

2

This arrow function takes no arguments but the request in the step is that it take a single argument and return it

3

Also you don’t need a comma at the end but you need it on the previous line

hi @juicethekidd

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
