An interesting syntax. Feels like something I'd only use for code golfing though lol. What's the performance comparison between using reverse, or using a standard for loop
In Java, I can't do negative indexing, so I always need to say "length - 1" to get the last element instead of just -1. This becomes annoying because for example if I wanted to split a string into an array and grab the last element (which might not always be the last character for example), I need to store the split results into a variable just so I can access the length, and then subtract 1.
Actually I guess python lists basically store the length as a property, so -1 is possible because you don't need to calculate the length separately.

Haha yeah on a regular basis I only use negative indexes to grab the last couple values in a list.
That's actually a really good question 🤔 It's 9 pm here so I'll look into it tomorrow and probably write another post it 💪
Negative indexing is a god-send.
