Abstracting effects with continuations
TL;DR
Errors can be effectively managed in programming by representing them as values, which enhances reliability. Continuations provide a way to abstract the details of computation, allowing developers to specify what to do once a value is available.
✦ Why It Matters
Implement continuations in your codebase today to streamline error handling and asynchronous operations.
Key Takeaways
- Use continuations to abstract different computation types.
- Maintain a single definition of business logic for various fetch strategies.
- Reduce code duplication by separating logic from effects.
- Implement a runner to handle specific fetching mechanisms.
How It Works
Continuations allow developers to define a generic structure for handling computations, specifying what to do with a value once it is available. This is achieved by wrapping the computation in a function that takes a callback, enabling flexibility in how values are fetched and processed.
