You can see the [LuaLearner's lesson](http://lessons.lualearners.org/lesson?id=86) on those loops. Shawnyg 4251 — 7y

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.
