In programming, homoiconicity a property of languages in which programs are represented as instances of a data structure of a primitive type of the language. This takes advantage of the fact that the information of programs and data can be carried through the same medium by storing a program’s code in a form that the language knows how to access and manipulate.
This can make metaprogramming much easier than it otherwise would be. A good example of a language exhibiting homoiconicity is LISP, where everything is represented as a list (S-expression). Since both programs and data are stored as lists, a LISP program can manipulate another program as easily as it would any data.
