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.

Finding a Path As a Self-Taught Software Developer
I did some traveling around the western US in late 2022 to take stock of where my life was and where I was going. During that time I decided that I would go all-in with my coding education, and committed to learning the remaining material listed on those bootcamp syllabi that I had not yet studied – namely, connecting the pieces of the MERN stack; learning about automated testing and data structures & algorithms; and studying development paradigms & methodologies like Agile, Scrum & Kanban, and OOP design patterns & principles – as well as continue to develop my programming fundamentals on platforms like Leetcode and Codewars.

RegEx: Decoding the Symbols
My first encounter with regular expressions was in a solution for a coding problem on Codewars, specifically Count the smiley faces! Which asks you to count the number of smiley faces in a given array but the catch is each smiley can have 1 of 2 kinds of eyes (: or ;), may or may not have a nose represented by 1 of 2 symbols (- or ~), and 1 of 2 symbols (D or ) ) for the smile. In total there are 12 different combinations that are a valid smiley. I, being the young and naive programmer I was, hard coded all 12 of those faces and checked every element against that list. And it worked! But the top solution included some strange syntax that I had never seen before

Best resource to learn python?
@OP DO NOT go on the path of perfecting it and parting with your time and money. Go with Jake Vanderplas's whirlwind tour of python whirlwind tour of python to get some basics and then jump into the river codewars and swim upstream daily and religiously until you reach to katas level 5. You will be good to go. My personal experience.
