Thank You So Much. I've been flipping through hours of videos and documentations but still struggle to understand what the comparator function do. Your video definitely makes things clearer especially when you wrote out the if statements and have them return -1, 1, and 0. Everything just clicked.

I finally understood the sort method and comparator function but what I don't understand is how come this guy only has around 8K subscribers!?? Given the quality of the content, imo he should have atleast half a million subs
