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.

What's another way to write "for await" that is es6 compatible?
Given that the semantics of async functions are quite similar to generator functions, you can use a library the uses the latter to emulate the former – e.g.: https://github.com/tj/co

Promises: async/await vs .then(), how we got here and why I use both
Then after a while, we resorted to generator functions and cogenerators, which made async code feel like its synchronous, at the cost of wrapping it in a generator function, yielding every line and introducing a cogenerator library (for example co) to deal with unwrapping the promises like the following example, where we could just yield a promise whenever we encounter it and pretend that the yield does not exist on that line of code.

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.
