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.
