The article provides guidance on the Candy Machine problem from the book "Functional Programming in Scala," emphasizing the significance of curried functions in managing state updates. It illustrates how a simple update function can transform a locked machine to an unlocked state with a coin input. By currying, the article expounds how functional programming distinguishes between the definition and execution of computations, paving the way for functional state actions which modify the machine state seamlessly. The author also aims to support readers grappling with Scala concepts in the book.
The goal of the Candy Machine problem is to differentiate between the definition of a computation and its execution through functional programming.
Currying allows for pre-baking functions, enabling transformation definition ahead of time in functional programming.
