Lua is an open source programming language.[2] It was created in 1993 by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes.[1] Lua is used for many different things, especially in video games such as World of Warcraft and SimCity 4.[5] It is also used in the popular virtual world sharing website Roblox under a dialect called Luau.[6] 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.[7] 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.[8]
