To be reactive, that's the answer!
summary
Shows a concrete Angular + RxJS path: a canvas that draws three points, computes a parallelogram and matching circle, implemented first imperatively then refactored to streams; uses hot vs cold observables, operators like debounceTime map take forkJoin retry and catchError, and BehaviorSubject for loading state; discovers subjects close on error and break a modal flow, refactors to pure observables so parallel requests return faster and the modal recovers successfully.
