MONADS - CODING FUNCTIONALLY

on YouTube ↗31m

" summary

Presents concrete JavaScript implementations of functors and monads (of/map/flatMap), demonstrates Maybe and Either patterns to handle nulls instead of try/catch, and treats Promise as a monad with chaining examples. References the fantasy-land spec and V8 internals' monad-like containers, and runs live code demos while noting the examples are practical but not yet production-deployed with caveats about real-world adoption.
