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.

Having too many contexts - is it a problem?
Use jotai, or as someone else mentioned, zustand. React Context out of the box requires a very deliberate mental model due to a lack of tooling around selecting slices of state. This is why packages like react-context-selector exist: https://github.com/dai-shi/use-context-selector

Truly the best time to be a cs student
Unless I've missed it, context doesn't have selector IIRC. You'd have to use a third party solution useContextSelector

Tips for managing and organizing complex state with React context
you can always split out context state or use a library to help with rerender issues like https://github.com/dai-shi/use-context-selector, or just switch to jotai or something else if you want something more ergonomic or better design patterns.

ReactJs - Useless re-renders when a context changes - HOW TO SOLVE IT ?
If you don't want to swap out useContext, you could always use useContextSelector, which helps you limit what props in the context should rerender the component.

-
is Redux the first state management library you'll advise beginners to learn these days?
It wouldn't be clear to anyone learning Context API either. At least, not using official docs. Because Context API is not supposed for state management, and if you for some unknown reasons try to roll your own state management on top of it, you have to use tricky libraries to work around the issues resulting from such abuse.

What are some React Tricks/Tips for React Devs?
Any time anything in the context changes, any component that is consuming it will re-render. If you use it for frequently changed values, this library is needed to reduce unnecessary re-renders.

Inflist, an experiment using PureScript and React
Another technology I use regularly is Redux. But this time I wanted to manage the global state in a simpler and clearer way just using React hooks. I decided to go with a simple useReducer combined with theuseContextSelector hook which will avoid the whole application’s re-render caused by the native useContext hook.

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

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.

[AskJS] Where will I need to write generator functions?
redux-saga makes use of them in really nice way. https://redux-saga.js.org/ That’s where I’ve used them the most.
