Resize Observer can be used to get a callback when container dimension changes. It listens for native resize events but throttle it using requestAnimationFrame. Note: This function might not resize the window synchronously. The benefit is, that it limits change detection cycles (it will trigger only when you run the callback in the zone), while (window:resize) will trigger change detection every time it gets called. The operators offer buffering similar to RxJS buffer RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code.
