Lua is an open source programming language.[1] It was created in 1993 by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes.[2] Lua is used for many different things and is widely used in video games such as World of Warcraft.[5] In June 2010, Apple Inc. changed the terms of use for the software development kit of its iOS operating system to allow the use of Lua.[6] This led to Lua being used to make iPhone applications such as Angry Birds. In June 2011, Lua was ranked the tenth most popular programming language by the TIOBE Index.[7]
