Demystifying the Trinity: Functor, Applicative, and Monad in PureScript
The article explores the concepts of Functor, Applicative, and Monad in PureScript, highlighting their roles in functional programming. It emphasizes that these abstractions are essential for managing data flow and computation in a mathematically sound manner. Practical examples illustrate how these concepts can be applied to handle values within contexts effectively.
- ▪Functors allow the application of pure functions to values within a context.
- ▪Applicatives extend Functors by enabling functions that are also wrapped in contexts to be applied to other wrapped values.
- ▪Monads provide a way to chain operations on wrapped values, allowing for more complex data manipulations.
