The article explores using continuations in the Gleam programming language to abstract computational effects like errors and asynchronous operations, demonstrating how they generalize patterns such as Result and Promise types. It provides a practical example of refactoring a simple data fetching function to handle these effects more flexibly.
Background
Continuations are a fundamental concept in functional programming that allow a program to capture its current state and resume execution later, often used to implement complex control flow. This technique is particularly relevant in modern languages seeking to unify error handling and asynchronous programming models.
