COMMUNITY QUESTION
What's the difference between a numeric for loop and a generic for loop?
1 answer
Basically, a numeric for loop loops over a certain array of numbers with a certain increment. For example, for x = 1,5,2 do print(x) end will print 1, 3 and 5.
A generic for loop is another type of for loop. You basically use the for loop as iterator again, but now you will use a function to get the values. One of the most used functions for a generic for loop is pairs(). This will slide a table index and it's value to the values;
local tab = game.Workspace:GetChildren()
for index, instance in pairs(tab) do
print("Instance number: "..index.." of game.Workspace has name: ".. instance.Name)
end
This will print all names of all children of workspace.

You can see the LuaLearner's lesson on those loops.
