If you're storing a lot of data in a structured way, it's useful to know your options for retrieving that data … WebLua's standard library and most modules written for Lua assume 1 as the first index for sequences. A gapless array therefore has items from 1..n without missing any numbers in the sequence. (In the limiting case, n = 1, and the array has only one item in it.) Lua provides the built-in function ipairs to iterate over such tables. fehérvár travel alapítvány
