Promises vs Observables
Developers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers meets 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. Here's our take.
Promises
Developers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers
Promises
Nice PickDevelopers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers
Pros
- +They are essential in JavaScript for avoiding 'callback hell' and are widely used in modern frameworks like React and Node
- +Related to: async-await, javascript
Cons
- -Specific tradeoffs depend on your use case
Observables
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
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
The Verdict
Use Promises if: You want they are essential in javascript for avoiding 'callback hell' and are widely used in modern frameworks like react and node and can live with specific tradeoffs depend on your use case.
Use Observables if: You prioritize 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 over what Promises offers.
