Native Lua statement:
Used in loop constructs to iterate through the values of a table where the index are only numbers, or where there is no index (an array).
Example:
local fruits={"apple","orange","banana","kiwi"}
for index,value in ipairs(fruits) do DEFAULT_CHAT_FRAME:AddMessage(tostring(index).." : "..value) end
Result:
1 : apple 2 : orange 3 : banana 4 : kiwi
would be output to the chat window.
