How can I see if a name exists in a table, without having to iterate through every value?

local PlayersData={
	['MessorAdmin'] = "derp";
	['AwseomeSpongebob'] = "Hellooooooo? nub?"
}
 -- Alright, here's our table.

We want to print our data right? Lets go ahead and do that now. There's a few different ways. Way 1:

Not meant for new games, it's deprecated.

table.foreach(PlayerData, print)

Way 2:

for i,v in next,PlayerData do
	print(i, v)
end

Way 3: Now, if you don't want to go all the way through all the datas just use this.. But be careful, this is prone to errors.

local Result;
if PlayersData['MessorAdmin'] then
	Result = PlayersData['MessorAdmin']
else
	Result = "Aww :("
end
print(Result)
