What is unpack used for?
Unpack is used for separating values in a table for example
local Table = {"g","o","o","d","a","d","m","i","n","s"} -- This is my Table
print(unpack(Table)) -- This unpacks the table and prints it as separate values
Output
g o o d a d m i n s
This prints all the content of the table in one line
local t = {"1","2","3","4","5"}
print(unpack(t))
Above code prints out each element in 't', starting from index 1. A brief explanation would be as follows:
unpack is a special function in Lua which receives a specified table and returns the elements in that table in consecutive order, starting from index 1.

They're called elements not "content"
Actually the things inside the table are the tables 'content' smart kid
I can’t tell if you’re serious or not, first you downvote a correct answer then you refer to elements as “things”
