Coroutines explained
summary
Explains coroutines by showing concrete code in Lua resume/yield, JavaScript generators and async/await -> state machine and call/cc continuations in Scheme, with timings (2s and 5s promises produce a 7s composed result) and runnable patterns. Demonstrates wrapping callback APIs into promises (readPromise) to flatten nested callbacks, shows that async/await compiles to a state machine, warns that generators can leak resources because finally runs only on exhaustion and that stackful vs stackless semantics affect where and how suspension and resumption happen.
