Continuations vs Promises
Developers should learn continuations when working with languages like Scheme, Haskell, or Scala that support them natively, as they enable powerful abstractions for non-local control flow, such as implementing backtracking algorithms, web server continuations for asynchronous handling, or custom control operators 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.
Continuations
Developers should learn continuations when working with languages like Scheme, Haskell, or Scala that support them natively, as they enable powerful abstractions for non-local control flow, such as implementing backtracking algorithms, web server continuations for asynchronous handling, or custom control operators
Continuations
Nice PickDevelopers should learn continuations when working with languages like Scheme, Haskell, or Scala that support them natively, as they enable powerful abstractions for non-local control flow, such as implementing backtracking algorithms, web server continuations for asynchronous handling, or custom control operators
Pros
- +They are particularly useful in compiler design for implementing advanced features like call/cc (call-with-current-continuation) and in functional programming to manage complex state and execution contexts without side effects
- +Related to: functional-programming, scheme
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 Continuations if: You want they are particularly useful in compiler design for implementing advanced features like call/cc (call-with-current-continuation) and in functional programming to manage complex state and execution contexts without side effects 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 Continuations offers.
