A, B, C. 1, 2, 3. Iterables you and me
summary
Explains how JavaScript implements the iterator and iterable protocols and shows concrete code: a range implemented first as an iterator then as a generator, a custom map/filter/take pipeline built over iterables, and an async variant using generators and async generators. Demonstrates laziness: the pipeline processed only five items instead of generating all 19/22 intermediate values, shows for-await-of for async pulling, and links a working proof‑of‑concept repository for state/side‑effect management using iterables.
