Monad for dummies - Gina Peter Banyard

Php

Discover the world of monads in a simple and easy-to-understand manner. Learn how monads can help manage state and side effects, handle errors, and create compositional code in functional programming.

Key takeaways

A monad is a structure that combines functions with one parameter set to two, allowing them to be composed together in a predictable way.
Monads are not just about error handling, but also about creating a way to manage state and side effects in a functional programming way.
The Maybe monad is a basic example of a monad that represents the possibility of a value not being present.
The IDA monad is another example of a monad that represents two values, one for each side of the monad.
A functor is a type that can be mapped over, allowing functions to be applied to its values.
A bind function is a key part of a monad, allowing the monad to be composed with other functions.
Monads can be used to handle errors in a predictable way, by wrapping the result of a function in a monad and then binding it to a success or failure handler.
Monads can also be used to create a way to manage state and side effects in a functional programming way, by wrapping the state and side effects in a monad and then binding them to a function.
A category is a way to classify things, such as types in PHP.
A category can be used to define a way to map values from one type to another, allowing functions to be composed together in a predictable way.
Monads are a way to work with categories in a functional programming way, by creating a way to manage state and side effects and handle errors in a predictable way.
Functional programming is a way of programming that focuses on the use of pure functions, immutability, and the avoidance of side effects.
PHP is an example of a language that is not naturally functional, but can still be used to program functionally.
The Maybe monad is used in PHP to handle the possibility of a value not being present.
The IDA monad is used in PHP to handle two values that are related, such as the left and right sides of a monad.
The bind function is used in PHP to compose monads together in a predictable way.
Monads can be used to handle errors in PHP by wrapping the result of a function in a monad and then binding it to a success or failure handler.
Monads can also be used to create a way to manage state and side effects in PHP, by wrapping the state and side effects in a monad and then binding them to a function.
