Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Comparing React state tools: Mutative vs. Immer vs. reducers
Immer is a lightweight package that simplifies working with immutable states. Immutable data structures ensure efficient data change detection, making it easier to track modifications. Additionally, they enable cost-effective cloning by sharing unchanged parts of a data tree in memory.

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!

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/)

Get out of state management hell with automatic revalidation
You add the current user state to a React Context or state management library, read from it on the top bar, and write to it after a user signs in. Done. No big deal, right?

Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes, and more
- Throws better errors in an RSC environment
- https://github.com/reduxjs/react-redux/releases/tag/v9.0.0
## Reselect 5.0:
- Switches to a new `weakMapMemoize` memoizer as default
- Renames `defaultMemoize` to `lruMemoize`
- Allows passing memoizer options direct to `createSelector`
- Many TS improvements
- https://github.com/reduxjs/reselect/releases/tag/v5.0.1
## Redux Thunk 3.0:
- Drops the default export and switches to named exports ( `{thunk, withExtraArgument}` )
- https://github.com/reduxjs/redux-thunk/releases/tag/v3.1.0
This has been a _huge_ year-long development effort!
We're thrilled to get these improvements out. The tooling and bundle improvements will help all users, and we think the features and TS changes will improve the Redux dev experience significantly.
Thank you SO MUCH to everyone who has contributed or helped test out the work!
Please file bug reports for the inevitable issues that pop up post-release!
but now I'm going off on a conf trip and going to take a very well-earned break from Redux work for December :)

I am making a pizza app and I want that whenever I click on add my cart gets updated which is at the bottom of the page. Can anyone please help
You should think about using some client state management libraries like Redux. Redux gives you the possibility to encapsulate states and manipulate it through functions. https://react-redux.js.org/
What are some alternatives?
immutability-helper - mutate a copy of data without changing the original source
axios - Promise based HTTP client for the browser and node.js
immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity.
Express - Fast, unopinionated, minimalist web framework for node.
redux-toolkit - The official, opinionated, batteries-included toolset for efficient Redux development
recompose - A React utility belt for function components and higher-order components.
Recoil - Recoil is an experimental state management library for React apps. It provides several capabilities that are difficult to achieve with React alone, while being compatible with the newest features of React.
reselect - Selector library for Redux
react-query - 🤖 Powerful asynchronous state management, server-state utilities and data fetching for TS/JS, React, Solid, Svelte and Vue. [Moved to: https://github.com/TanStack/query]
kea - Batteries Included State Management for React
valtio - 💊 Valtio makes proxy-state simple for React and Vanilla
