The for statement has two variants: the numeric for and the generic for. A numeric for has the following syntax: for var=expexpexpdo something end. That loop will execute something for each value of var from expto exp, using expas the step to increment var. One can be used to iterate through a numeric progression and the other can be used to iterate over functions called iterators.

More About the Generic for Loop So far whenever we have used the pairs (tbl) or ipairs (tbl) functions it has been with the generic for loop. Both return an iterator function that does the hard work.
