To track side effects in functional programming, you can use an algebraic effect type system to explicitly define effect signatures and track operations, ensuring computations remain predictable and maintainable.

Algebraic effects are a formal system for managing computations with side effects. They enable extensible effects by allowing you to declare effect types, track operations, and handle effects via dedicated handlers.

You can infer effect types by applying an effect type system that evaluates the algebraic effect signatures within your code, automatically determining the side effects associated with a specific expression.

You need a formal system to manage side effects when developing complex systems involving operations like logging, state management, or I/O, ensuring these effects are explicitly managed to prevent unexpected behavior.

Yes, effect handling mechanisms allow you to implement custom handlers for declared algebraic effects, providing an extensible way to intercept and manage specific side effect operations within your program.
