Explore the distinctions between promises and observables when handling AJAX requests in RxJS. Learn how observables enable multiple values, enhanced error handling, and retries to improve user experience, especially in unstable network conditions. Understand how to integrate promises with observables and why maintaining a consistent abstraction benefits your codebase.
