Transient Mutation
Explore the concept of transient mutation in PHP functional programming to control external state changes during immutable result production. Learn how to apply the TransientMutator trait in value objects to optimize iterations and improve efficiency while maintaining functional paradigms.
Overview
When a function produces an immutable result, it’s always possible that it modifies an external state in the process. This is especially visible in value objects and persistent data structures where artifacts, such as iterative control structures, create multiple encapsulated data structures before producing a single result. Transients allow for the exertion of control in situations where some form of mutation is common and offer a ...
