How To Build Your Own RxJS Operators
summary
RxJS reports 8.7 million npm downloads per week and ships 6.5.1 with new helpers like fromFetch and forkJoinObject plus a new scheduled helper; a roadmap toward RxJS 8 promises ~60% smaller CLI footprints. Concrete code: examples build an everyNth operator, a reusable logError/http operator, and a map implemented from scratch showing try/catch for user functions and lift semantics. Tests use TestScheduler marble tests and practical guidance on when to use them.
