Immer VS mutative - a user suggested alternative

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework
```
It looks like it’s mutating, but both the reducers and update() uses immer* under the hood, so we still respect immutability under the hood.
Cami supports redux devtools so you can use that for time-travel debugging too!

Making Sense of React Server Components
I heard that immutability libraries like immer.js [0] help with this. Anyone go this way and had good success? Is this 'the way'?

How We Fixed Performance With JS Object Variable Mutation
So, that's what we built, and we built it in the most obvious way — using JavaScript Proxy objects to track mutations and reflect those changes across Appsmith’s framework. Initially things looked good — it worked, aside from a few hacks to make some data types work with map and set, and we were following the example of other projects that had similar requirements. If it was good enough for them, it should be good enough for us, right?

The sword refers to immer, the faster and stronger immutable data js tool limu stable version released!
But is immer really the ultimate answer? The performance problem of immer is more prominent in large arrays and deep-level object scenarios. See this issue description, many authors in the community began to try to make breakthroughs, and noticed that structura and mutative, I found that it is indeed many times faster than immer as they said, but it still fails to solve the problem of both fast speed and good development experience. I will analyze the two issues in detail below.

Ramda: A practical functional library for JavaScript programmers
I like immer for this kind of thing: https://github.com/immerjs/immer
It gives you immutable updates without getting bogged down in FP abstractions.

Why my variable is being mutated if I make any changes to my data ?
I've always been a huge fan of immer for these case. For your code, it would simply turn into setGridData((prev) => produce(prev, draft => applyChanges(changes, draft)) but I recommend you go over their documentation to fully understand how it works

Is there a better way to do read-only types
If you're trying to make things actually immutable, Object.freeze and deep copies can clutter things up pretty good, have you considered using something like immer? (https://immerjs.github.io/immer/)

5 React Libraries to Level Up your Projects in 2023
If you want to set up from Context, Zustand is your best bet. It offers an extremely simple API that lets you create a store with values and functions. Then, you can access that store from anywhere in your application to read and write values. Reactivity included! If you want to store nested object data in your store, consider using Immer alongside Zustand to easily change nested state.

Copilot: Weapon For Laid Back Developers
In my example I am using Redux Toolkit and I got a prompt for actions to login and logout the user. If I need more functions, I can simply start typing the name, and Copilot provides the completion. For instance, in the example, I'm adding a function to update the user. And of course at the end of the file it suggests the exports.

Redux Toolkit 2.0

This Month in React Nov 2023 – Redux Toolkit 2.0, Kent v Lee, Prettier bounty
Redux Toolkit 2.0 is almost here! Hopefully shipping by this weekend :) Migration page
- Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes (plus major versions for all Redux family packages!)
-
Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes, and more
I am _thrilled_ to announce that:
Redux Toolkit 2.0 is LIVE!!!
- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0
This major version has new features, faster perf, smaller bundle size, and removes deprecated options.
It's accompanied by majors for all our Redux family packages
## RTK 2.0:
- a new `combineSlices` method for lazy-loading reducers - Updates to `createSlice` to include a `selectors` field and allow defining thunks inside
- Immer 10 w/ faster updates
- Removal of deprecated options
See the migration guide:
- https://redux.js.org/usage/migrations/migrating-rtk-2
All of the Redux libraries now have modernized packaging with full ESM/CJS compat. They also ship modern JS (no transpiling for IE11), which means smaller bundle sizes.
We've also done byte-shaving work to shrink the bundles (extracting error messages, de-duping imports)
## Redux core 5.0:
- The TS conversion we did in 2019!
- Action types _must_ be strings
- `UnknownAction` as the default action type
- Better preloaded state types
- Internal subscription improvements
- Still marks `createStore` as deprecated!
- https://github.com/reduxjs/redux/releases/tag/v5.0.0
## React-Redux 9.0:
- *Now requires React 18 and RTK 2.0 / Redux 5.0*

Blogged Answers: My Experience Modernizing Packages to ESM
Oh hey, that's my post!
(yes I spend too much time refreshing HN :) )
FWIW I did end up with a packaging combination that seems to work sufficiently. I never did fix the "FalseCJS" issue that `are-the-types-wrong` is detecting. I played with double-emitting TS typedefs, and the `tsup` tool _does_ actually have support for that now (added by Andrew Branch from the TS team). So it might be more feasible now. But ultimately I decided I was tired of messing with packaging setup and that what I've got is good enough. (hopefully)
We're actually about to launch Redux Toolkit 2.0 and Redux 5.0 this week, assuming the last couple pieces come together. Here's the latest RCs - you can see the current `package.json` files in there:
- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0...
- https://github.com/reduxjs/redux/releases/tag/v5.0.0-rc.1

Setting up Redux Persist with Redux Toolkit in React JS
However, Redux, or pure Redux to be specific, can be quite verbose and boilerplate-heavy. It requires a significantly lengthy setup, which is where Redux Toolkit comes in handy, offering a simplified and more efficient way to set up and manage state in your React applications.

44 React Frontend Interview Questions
State manager is a tool or library that helps manage the state of an application. It provides a centralized store or container for storing and managing data that can be accessed and updated by different components in the application. A state manager solves several problems. Firstly, it is a good practice to separate data and the logic related to it from components. Secondly, when using local state and passing it between components, the code can become convoluted due to the potential for deep nesting of components. By having a global store, we can access and modify data from any component. Alongside React Context, Redux or MobX are commonly used as state management libraries. Learn more Learn more
