Tell us what’s happening:

I don’t know what I’m doing wrong

Error messages are as follows:

// running tests
3. Your even function should take a nums parameter.
5. Your even function should return the result of calling the .filter() method on nums.
6. You should pass a reference to your isEven() function as the callback for the .filter() method.

The code:
spreadsheetFunctions.even(nums) => nums.filter(isEven)

Hi @dreyes61

Add an even property to your spreadsheetFunctions .

Since the spreadsheetFunctions object is declared using a const keyword, you need to update the object directly.

Happy coding
