State of RxJS
summary
RxJS announces v7 beta with concrete changes: improved TypeScript 3.8 type inference (rest args now infer beyond nine), creation of animationFrames, and new promise APIs lastValueFrom / firstValueFrom replacing toPromise with clearer empty-rejection semantics. The library adds async iterable support (consume async generators as sources), retry with resetOnSuccess, reduced scheduler footprint via a timestamp provider defaulting to Date, many deprecations (result selectors, scheduled args, multi-arg subscribe), and plans for ESLint/codemod migrations toward a much smaller v8.
