Enumerating and analyzing 40+ non-V8 JavaScript implementations
The concept known as "worse is better" holds that in software making (and perhaps in other arenas as well) it is better to start with a minimal creation and grow it as needed. Christopher Alexander might call this "piecemeal growth." This is the story of the evolution of that concept.
What is threaded code? What is it good for? What are the differences between the various threading techniques? How do I implement threaded code portably? How fast are various threading techniques?
