Paradigms for dealing with asynchrony
summary
Compares concrete tradeoffs between callbacks vs promises vs observables vs CSP, shows code from a Khan Academy app where an exercise task flow is implemented two ways, and reports a small visualization library was prototyped but abandoned; notes Node is changing unhandled promise behavior and Chrome 55 adds native async/await, and demos js‑csp generator style code that blocks on yields. Emphasizes which primitives cache values, how many values they carry, who can cancel or write, and where mental overhead or debugging pain actually appears.
