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.

Focusing on optimization, surpassing immer, limu finally reaches the top of immutable data performance
helux A state engine that integrates atom, signal, and dependency tracking, and supports fine-grained response updates
- Helux, a react state lib supports both atom arch and deep dependency collection

The sword refers to immer, the faster and stronger immutable data js tool limu stable version released!
At the end of 2021, I started to conceive the v3 version of the state library concent, one of the key points is to support deep dependency collection (v2 only supports the first collection of state One-layer read dependency), then you need to use Proxy to complete this action in depth, and use immer in depth to find that viewing drafts in debug mode is very frustrating, and you need to use JSON.parse(JSON.stringify(draft)) to complete, although it was later discovered that the current interface can export a draft copy and view the data structure, but it really annoys me to insert extra current and then erase it at compile time, and current itself has a lot of problems Overhead, plus the following similar performance problems of immer found through issue

Limu, a Fast Immutable Lib
Why is Limu born? Because I plan to release concent V3 next year, I need a more advanced immutable data JS operation tool, so Limu was born

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!

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/)
