It is most prominent as a [[performing arts]] form and a [[creativity technique]] centred upon the writing of [[source code]] and the use of [[interactive programming]] in an [[improvisation|improvised]] way. Live coding is often used to create sound and image based [[digital media]], as well as light systems, improvised [[dance]] and poetry,<ref>Magnusson, T. (2013).

The figure of '''live coder''' is who performs the act of live coding, usually "artists who want to learn to code, and coders who want to express themselves"<ref>{{cite web|last=Bell|first=Sarah|title=Live coding brings programming to life - an interview with Alex McLean|url=http://www.britishscienceassociation.org/blog/live-coding-brings-programming-to-life-an-interview-with-alex-mac|accessdate=2 March 2016}}</ref> or in terms of Wang & Cook the "programmer/performer/composer".<ref name="auto"/>

"Temporal recursion" was a term initially coined in relation to the [[Impromptu (programming environment)|Impromptu]] programming environment. Technical elements within a programming environment continue to locate compressors and recursion solutions, but timing had been a major issue. While the general form of a temporal recursion, being any asynchronous function recursion through time, is available to any event driven system, Impromptu has placed a special emphasis on this particular design pattern,<ref>Sorensen, A & Gardner, H (2010) "[http://eprints.qut.edu.au/55712/1/sorensen_ow_2010.pdf Programming With Time: Cyberphysical Programming In Impromptu, In proceedings of the ACM Splash Conference 2010]"</ref> making it the centre piece of the concurrency architecture on that platform. Temporal recursion had repeatedly been used in [[SuperCollider]] and has since been implemented in the [[Fluxus (programming environment)|Fluxus]] environment.

Another functional approach to the representation of time is shown in the [[Tidal (livecoding)|Tidal]] pattern [[Domain-specific language|DSL]],<ref>{{cite book|last=McLean|first=Alex|chapter=Making programming languages to dance to: Live Coding with Tidal|url=https://github.com/yaxu/Tidal/blob/master/doc/farm/farm.pdf?raw=true|title=In proceedings of the 2nd ACM SIGPLAN International Workshop on Functional Art, Music, Modelling and Design|year=2014|___location=Gothenburg}}</ref> which represents patterns as combinators operating over functions of time, similar to techniques in [[functional reactive programming]].<ref>{{cite web|last=McLean|first=Alex|title=Tidal homepage|work=Alex McLean |url=https://yaxu.org/tidal/|date=2013-08-02}}</ref>
