Lua's tables can be used to represent arrays, with integer keys and consecutive indices starting at 1. Here's an example:
local my_array = {"apple", "banana", "cherry", "durian"}
for i = 1, #my_array do
print(my_array[i])
end
In this example, my_array is an array of strings. The for i = 1, #my_array do line loops over each element of the array using its index.
