Can someone explain to me/help me what. for i,v in pairs do. Does? Help me please :D

Oh God! It was a pain in the butt for me too! Even though it is very easy, it took my while. Alright so, I'll try to describe as easy as I can.

In every programming language including Lua, there are arrays(Or tables) and those tables have two main things. An index and a value(This is where i and v comes from. i stands for index, v stands for value but you can change those as you wish.)

You can reach value by using TableName[IndexValue] easily but most of the times you will encounter with tables that you don't know what index is but you still have to reach it. Array indexs aren't always straight like 1,2,3, they can be like 1,5,9,"lol","xd",333. That's where In Pairs comes.

So, let's create a table first.

local OurTable = {} --First, creating an empty table.
OurTable["EnomphiaMoney"] = 500 --Equaling index "EnomphiaMoney" to 500
OurTable["superalp1111Money"] = 1337 --Equaling index "superalp1111Money" to 1337

Now we can't just reach arrays with a NORMAL for loop. Normal for loops are loops that counts from a starting value to ending value with an increment. That's why we are going to use in pairs. I will tell it more detailed after writing the code.

for a,b in pairs(OurTable) do --As I said, you can change variable names. I prefer a and b
    print("Value for "..a.." index is: "..b)
end)

So basically, this prints index and the value that table has for that index. Output would be:

Value for EnomphiaMoney index is: 500
Value for superalp1111Money index is: 1337

I hope I could tell it good! It's very useful thing for tables.
