What can 'for i, v in next, list do' be used for?
Hello everyone, I recently came across the for i, v in next variant of the for loop and was wondering if its only use was to loop through a list? After experimenting, I found it worked similarly, if not the same as for i, v in pairs? If not, what can it be used for that pairs cannot?
local example = {"apple", "banana" ,"carrot", "burger"}
for i, v in next, example do
print(v)
end
Output from pairs;
apple, banana, carrot, burger
Output from next;
apple, banana, carrot, burger

It just cycles through a table giving its index and its value. For example this is useful for verification or other things to do with verifying.
Edit: I think their the same thing. I use next for everything, cause that's just me.
Example 1:
local AllowedPlayers = {"BradNewTypical", "Utter_Incompetence"}
for i,v in next, AllowedPlayers do
if game.Players.LocalPlayer.Name == v then
print("Allowed")
end
end
Example 2:
local Ranks = {
["owner"] = "Utter_Incompetence",
["admin"] = "BradNewTypical"
}
for i,v in next, Ranks do
if game.Players.LocalPlayer.Name == v then
if i == "owner" then
print("Hey it's an owner")
elseif i == "admin" then
print("Hey it's an admin")
end
end
end
Good for admin commands, I guess and other things.
