How do I use "for i,v in pairs("") in a script?

for i,v in pairs() is used whenever you want to loop through a table or dictionary. For example:

local MaTable = {“Thing 1”, “Thing 2”, “Thing 3”}

for i,v in pairs(MaTable) do – this will go through “Thing 1”, “Thing 2” and “Thing 3”

the i and the v in the loop is variables for the loop. i stands for how many time the code have gone through the table

for i,v in pairs() do
print(i)
end – this will print:
1
2
3
Because it looped through the table three times.

the v in the loop stands for what item the code is on

for i,v in pairs(MaTable) do
print(v)
end – this will print:
Thing 1
Thing 2
Thing 3
Because those are the items in the table
