2. Live Coding
   Live coding (sometimes referred to as
   ’on-the-fly programming’, ’just in time programming’, and
   ’conversational programming’) is a performing arts form
   and a creativity technique centred upon the writing of
   source code and the use of interactive programming in
   an improvised way.
