enjoying the videos...thank you for the help on understanding these problems, how long did it take you to get this comfortable with these linked list problems

i am having a tough time understanding linked lists, can you explain me why is the result itself passed as the "next" parameter to the new Node, how does that work?

Any reason you create a new Node class instead of using the ListNode provided by the problem?

Runtime complexity of JavaScript's arr.sort is O(nlogn) in average case so your solution is not O(n) time. Nor is your space complexity O(1), because you're creating not only temp integer array but also new nodes from the array. Your space complexity is 2n so O(n). I almost never comment on videos but you were wrong on all fronts in terms of complexity analysis, and hopefully my comment prevents any clueless person from getting misinformed by this video.
