Additional Notes
How would you explain the tradeoff of using CompletableFuture for network calls in an interview?

Java: Jackson ObjectMapper
Answer
CompletableFuture improves responsiveness but can increase code complexity.
Using CompletableFuture allows non-blocking, asynchronous execution, which can significantly improve application responsiveness, especially in scenarios with long network calls like fetching user reviews from an API. However, it can make error handling and debugging more complex, requiring careful design to manage execution flow and exceptions.
