Length Operator

The length operator stops at the last index in an array, not at the first index of nil, that is ipairs. say, for example, i had a table like:

local arr = {1,nil,nil,nil,4}

getting the length of array arr with the length operator (#) would return

5

however, if a table was like:

local arr = {1,[10]=45}

getting the length of array arr with the length operator would return

1

This is due to the way the length operator works. In lua, the length operator returns the last numeric key whose value is not nil for tables starting from 1.

Addition

I feel that count guge the cool did a great job of explaining this on the discord server, but I will be trying to emulate that here:

? is the last element of the array part nil
if no
	?is the hash part empty
	if yes
 		return the array size
	if no
		return the result of an unbound search
if yes
	return the last non-nil index visited in a binary search

Hopefully this helped!
