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.

Creating Own Chat GPT
For the backend, we chose Python, Django Rest Framework. On the frontend, React, Redux, Saga, Sass. Let’s start with the backend, which was managed by Yegor. He writes about the server part of the project himself.

Internals of Async / Await in JavaScript
The whole article properly the best explanation of generators I have come across. This quote stuck out:
> Generators are a special type of function that can return multiple pieces of data during its execution. Traditional functions can return multiple data by using structures like Arrays and Objects, but Generators return data whenever the caller asks for it, and they pause execution until they are asked to continue to generate and return more data.
Applications of generators? I have only used Redux-Saga[1]. Can't even think of other libraries that use them, but would be interested in learning.

I don't get why I should use Redux
Redux can be extended with a lot of other packages. For example with a side effect manager, you can separate side effects from your business logic, help with error handling and in the same process make testing of side effects a lot easier.

Front-end Guide
Your app will likely have to deal with async calls like making remote API requests. redux-thunk and redux-saga were created to solve those problems. They may take some time to understand as they require understanding of functional programming and generators. Our advice is to deal with it only when you need it.

Why Would Anyone Need JavaScript Generator Functions?
Hey thanks for the thoughtful response.
I agree with everything you mentioned here. I'd love to continue to chat with you about how to make testing sagas better.
If you'd like, it would be great if we could move this convo to https://github.com/redux-saga/redux-saga/discussions/2337
Redux-sagas[0] makes great use of generators. I found it a fantastic tool, if you're already in the redux ecosystem, and have an application that sprawls enough to benefit. It's great when you have to manage multiple process lifecycles. A single "saga" can represent the entire lifespan of a session in just a few lines of code, a socket or similar long-lived process, with clear code branches to shorter-lived handlers or other sagas for the details.
The downsides are:
- a quirky syntax that needs learning, and is of the "loose with semantics" style - like Rails-eque REST's play with HTTP methods
- it's hard to test (despite what the documentation claims). It's highly declarative, and such code seems hard to test.

What is the best plan to catch data from multiple api calls and display some data
If there are dependent API calls, you can probably look at redux-saga. It’s one of the best libraries out there to manage the data.

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'?

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.

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.
