    https://redux-toolkit.js.org/ uses immer.js in its `createReducer` and `createSlice` methods. In my opinion this makes working with redux easier, as there is much less code to read/write. – ksav Jul 15 '21 at 06:15

From the Immutability Helpers docs:

update() provides simple syntactic sugar around this pattern to make writing this code easier.

While the syntax takes a little getting used to (though it’s inspired by MongoDB’s query language) there’s no redundancy, it’s statically analyzable and it’s not much more typing than the mutative version.

It's an advanced solution than Object.assign() and spread operator (...).

There is also a more advanced solution for updating state. - immerjs

You don't need to care and write too much shallow copy code to update the nested states.

With the increasing performance of machine devices, the performance issues of reading and writing states can be almost disregarded for general applications. Priority should be given to improving development efficiency, reducing code redundancy, and improving code reusability, readability, maintainability, and extensibility.

Immutability Helpers and immerjs and other similar libraries are designed to solve this problem.
