Effect-Oriented Programming
summary
Introduces Effect-Oriented Programming with runnable examples in Scala/ZIO and a TypeScript effect library, showing concrete results: a random-word pipeline using collectAllPar to fetch N words in parallel, a flaky save that retries twice and succeeds on the third try, a 5s timeout that produces a timed-out error, finalizers and fallback queues, tests that feed deterministic random booleans, repeat a test 10 times, and advance a simulated clock to avoid a 24-hour wait.
