It enables asynchronous programming, allowing tasks to run without blocking the main thread.
CompletableFuture allows you to execute tasks asynchronously, making it possible to perform time-consuming operations in parallel without holding up the main program flow. For instance, in an e-commerce site, processing user payments and sending confirmation emails can be done concurrently, improving the overall user experience.
