Data Accessing Question

[gaunt fractal]

I know you can access the first element of an array using /data (get/modify/remove) (storage/entity) path[0], but is there a simple way to access the last element of an array?

theres a way i can implement what im doing that doesnt require it, but it'd make the end result a bit less fun, so i'd prefer to be able to do that

honestly i could use some documentation on minecraft's data structure in general im not sure where to find that

oh wait just remembered the datapack wiki exists

that has general information on the data structure

doesnt answer the main question though

i suppose i could just track the length of the list independently as i add and remove items and macro that into the index value if there isnt a better solution

you can access the last element of an array by using [-1]
