An array of Lua

Lua arrays

arrays, which are collections of elements of the same data type arranged in a certain order, can be one-dimensional and multidimensional arrays.

The index key value of the Lua array can be represented by an integer, and the size of the array is not fixed.

Array = {"Lua", "Tutorial"}for i= 0, 2 do print (Array[i]) end

The For loop pattern starts with the subscript starting at 1, so the initial value of I is set to 0 by default
