摘要：Not only will we need to give our initial state to a Redux store, we will also need to be able to reset our state at any time by dispatching an action

摘要：By using the State ADT to define how our application state transitions over time, we clear up the need for a some of the boilerplate that we typically

摘要：When we start to accumulate functions that all work on a given datatype, we end up creating a bunch of boilerplate code in almost every function to ha

摘要：When building our stateful computations, there will come a time when we’ll need to combine two or more state transactions at the same time to come up

摘要：We explore a means to represent the combination of our stateful computations using familiar composition. We dive into what makes this possible by talk

摘要：Stateful computations require the ability for their state to change overtime. We take a look on one way to replace the state portion of our stateful d
