JavaScript implementation of HotDraw. HotDraw was invented by Ward Cunningham and Kent Beck at Tektronix in the 1980’s (and implemented in Smalltalk). Ralph Johnson has used HotDraw as a case study while arguing for Documenting Frameworks using Patterns (OOPSLA92): design patterns and pattern languages provide much of the documentation needed by someone wanting to use a framework to implement an application. Johnson and Kent Beck went further to claim that Patterns Generate Architectures (ECOOP94): design patterns determine all the interesting parts of the software architecture.
