It’s the length operator, used for getting the amount of index-value pairs in tables and length of strings.

It basically just represents the amount of items in a table. For example

local Table = {"Hi", 10}

print(#Table) -- 2

The # operator does not count all of the non-nil keys. It counts how long, from the key value 1, until it reaches a nil value. So, if 2 was nil and 1 had some value, it’d return 1.
