What is "i" and "v" in the "In Pairs"?
Whenever I use the In Pairs, I couldn't Understand the index, and the value, Like for example, I have a Box with a Car in it, would the Box(outside) be the index, and the value would be the Car INSIDE the Box?
Please Respect that I am a Scripter in need for Knowledge

It's kind of hard to explain, but:
1 | Table = { |
2 | Index = Value |
3 | } |
Index and value could be anything.
If an index isn't assigned but a value is, the index will be the length of the table + 1. For example:
1 | Table = {} |
2 | table.insert(Table, "hello") |
"hello" will have an index of 1 because the table is empty.

What if I wanted to just use the Value instead of the Index? Would I have to add a "_, Index"? woodengop 1134 — 10y

Using "i,v" is the same as "_,v". You can leave the index if you don't need it. Vlatkovski 320 — 10y

Index is the Interval, and Value is the value of the table. i and v are just variables for index and value. You can change them to whatever you'd like. Here's how pairs would look in a while loop:
1 | local tab = {"one","two","three","four","five"} |
2 |
3 | local i = 0 |
4 |
5 | while i < #tab do |
6 | i = i + 1 |
7 | v = tab[i] |
8 | end |
Here's an example of how the variables can be changed:
1 | local admins = {"Player","Player1","aquathorn321","TheContinentofEurope"} |
2 | local admin == "aquathorn321" |
3 |
4 | for number, player in pairs(admins) do |
5 | if player == admin then |
6 | print(admin.." Is an admin!") |
7 | end |
8 | end |
