React lets you use whatever style of data management you want, including mutation. However, if you can use immutable data in performance-critical parts of your application it's easy to implement a fast shouldComponentUpdate() method to significantly speed up your app. Dealing with immutable data in JavaScript is more difficult than in languages designed for it, like Clojure. However, we've provided a simple immutability helper, update(), that makes dealing with this type of data much easier, without fundamentally changing how your data is represented. ...

...Action types, action creators and the reducer's action handlers are mutually assigned to each other. Repatch's purpose is to create actions briefly. The simplest way to keep the immutable action-controlled dataflow and define actions briefly is by dispatching pure functions (as reducers) to the store.

...The library is particularly useful in large-scale React applications where maintaining consistent state updates is critical. It allows developers to write reducers and selectors that operate directly on immutable data while preserving compatibility with Redux patterns. By leveraging Immutable.js, redux-immutable can also improve performance through structural sharing and efficient updates.
