Reactive Programming with RxJS, introduction to CycleJS
summary
Shows RxJS by building an observable from scratch, then reproducing it with RxJS create, using map, filter, merge, delay, debounce, scan and handling errors and complete callbacks; demonstrates an HTTP request emitted once or twice depending on subscriptions and explains hot vs cold (putting fetch outside makes a single request); proves observables combine promise and iterator behavior, are “lazy” because they’re functions, and builds a working CycleJS counter app wired to DOM and HTTP drivers.
