yeah nevermind i think I found some issues lol

So many different Javascript methods and properties are not working in this kata. flat() isn't supported, reverse() isn't supported, and now its even saying .length isn't working. I copied and pasted my function into the console and it has worked with every array I've thrown into it so I am 99% sure my code isn't buggy. Does it really not support something as basic as .length? This one has been SO much fun to figure out but it's frustrating how many fully supported methods and properties can not be used
