The functions are good. However there are a couple of issues with this line. What would happen if you didn't pass in hogwarts as a parameter? What is the value of the result variable? Also, there's a spacing issue - Javascript convention is to have no space between the function name and the opening parenthesis for parameters.

In my case, the answer will be the same, because I use hogwarts inside my function. To use hogwarts as a parameter, I would write code differently to pass, for example, an array in parentheses as a parameter in declaring a function and use the array to filter members. The type value of the result variable is an object(be clear, an array).

Hello Andrew, In my case, the answer will be the same, because I use hogwarts inside my function.

Yes the hogwarts variable was declared globally so there was no need to pass it into the function. The function doesn't return anything so result will be undefined.

The destructuring implementation follows best practices and the core functionality works correctly, producing the expected output. However, there are a few areas that need attention. Please ensure all variable and function names use camelCase consistently throughout the code. Additionally, consider whether the intermediate variables are really required or if some could be removed. The indentation also needs a little correction. I'd suggest running the code through prettier or some other code formatter to address styling issues automatically.

Thank you for focusing my attention on intermediate variables. I removed variables that I used only once and those whose absence would not influence code readability.

Your new implementation is really good.
