I'm not quite sure what this does, and I think it has something to do with a table. I just want to know the purpose of this.
For example, I want to know what #list does in a portion of a follow script that some NPCS use.
local list = workspace:GetChildren()
for i = 1,#list do
--code or whatever
end

the # is for how long the list is... for example, suppose you have 5 items in a list, then for i=1,#list <-- # is "5" in this case because you have 5 items. Then you can use for i=1,5 to do whatever with it
