Algebraic Effects for the Rest of Us

- Algebraic effects are a programming language feature that allows you to handle effects (like errors or async operations) in a way that lets you resume execution after handling them, unlike traditional try/catch which terminates.
- They enable separation of the 'what' (logic) from the 'how' (effect implementation), allowing code in the middle of a call stack to remain unaware of effects, avoiding issues like 'function color' seen with async/await.
- In React, concepts like Suspense and Hooks are inspired by algebraic effects, using techniques like throwing Promises or mutable state to simulate effect handling without built-in language support.
