Functional Programming for Everyday Work: Myth or Reality?

" summary

A JavaScript front-end app is built from scratch that queries the NASA API and renders its collection as cards with title, image and description. The implementation uses functional composition (Ramda/compose), Maybe/Either-style safe contexts to handle nulls, dependency injection and lazy evaluation to control side effects, and automated tests; a missing lunar image case is fixed by wrapping that value in the safe context.
