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.

I Avoid Async/Await
Async/Await covers the 80% of use cases for async logic in JS. Most people aren't really using promises as multicast references. They don't call `then` in one place, hang on to the promise reference, then call `then` again somewhere else (perhaps to represent a cached value); they call `then` once on the reference because it's just a moment in a composite operation.
It's for this reason that I think this library[0] is the more appropriate abstraction for that same 80% of use-cases, as its more memory efficient since you can represent the same composite operation that generates multiple promise references with a single object (a unicast reference instead). I haven't learned Rust but apparently the author bases this on Rust's ownership principle.

Immer VS mutative - a user suggested alternative

Show HN: Cami.js β A No Build, Web Component Based Reactive Framework
```
It looks like itβs 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'?

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.

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.
