Eff is a functional programming language designed to handle algebraic effects and their handlers. It allows for modular and flexible management of side effects, enabling developers to define and handle effects such as state, exceptions, or I/O in a clean and composable manner.
About Eff
Eff was created in 2012 to explore and implement the concept of algebraic effects and handlers in programming. It aimed to provide a more modular and composable approach to managing side effects compared to traditional methods. The language was developed as part of academic research to advance the understanding and practical application of effectful programming.
Eff's strengths include its modular handling of side effects, flexibility in effect management, and clean syntax for defining and using effects. Its weaknesses are limited adoption, a smaller community, and fewer libraries compared to more established languages. Competitors include Haskell, OCaml, and Scala, which also offer advanced functional programming features and robust ecosystems.
