Observables vs Promises
Developers should learn Observables when building applications that require handling real-time data, event-driven architectures, or complex asynchronous operations, such as user interactions, API calls, or WebSocket connections meets developers should learn promises to manage asynchronous tasks like api calls, file i/o, or database queries without falling into 'callback hell'. Here's our take.

Observables
Nice PickDevelopers should learn Observables when building applications that require handling real-time data, event-driven architectures, or complex asynchronous operations, such as user interactions, API calls, or WebSocket connections
Pros
- +They are particularly useful in front-end development for managing state changes and data flow in a declarative manner, improving code readability and maintainability compared to traditional callbacks or promises
- +Related to: rxjs, reactive-programming
Cons
- -Specific tradeoffs depend on your use case
Promises
Developers should learn Promises to manage asynchronous tasks like API calls, file I/O, or database queries without falling into 'callback hell'
Pros
- +They are essential for modern web development, especially when working with frameworks like React or Node
- +Related to: javascript, async-await
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Observables if: You want they are particularly useful in front-end development for managing state changes and data flow in a declarative manner, improving code readability and maintainability compared to traditional callbacks or promises and can live with specific tradeoffs depend on your use case.
Use Promises if: You prioritize they are essential for modern web development, especially when working with frameworks like react or node over what Observables offers.
