The ShareReplay operator in RxJS is a great way to improve the performance of your stream by caching expansive operations and side effects and sharing results with new subscribers. However, you should use this operator carefully because it has a hidden pitfall that can introduce memory leaks even though you explicitly unsubscribe from your streams. From this video, you will learn how to use it safely and how it works under the hood. Enjoy watching and sharing this video with your colleagues if you find it useful!
