Could someone explain to me what unpack() does and what it is used for?
I've seen it here and there but never understood what it is used for, could someone explain what unpack() is for?

What is unpack used for?
Unpack is used for separating values in a table for example
1 | local Table = {"g","o","o","d","a","d","m","i","n","s"} -- This is my Table |
2 |
3 | print(unpack(Table)) -- This unpacks the table and prints it as separate values |
Output
1 | g o o d a d m i n s |
This prints all the content of the table in one line

They're called elements not "content" Theswagger66 54 — 5y

Actually the things inside the table are the tables 'content' smart kid Prestory 1395 — 5y

I can’t tell if you’re serious or not, first you downvote a correct answer then you refer to elements as “things” Theswagger66 54 — 5y

1 | local t = {"1","2","3","4","5"} |
2 | 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.
