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.

Class Static Initialization Blocks in JavaScript
If you often find yourself working with static fields you may find static initialization blocks to be a useful feature. They can help make static initialization easier. I hope that this post helped you understand what class static initialization blocks in JavaScript are and how to use them. If you want to learn more about this feature, you can take a look at the proposal available on GitHub.

Updates from the 85th meeting of TC39
Class Static Blocks Class static blocks provide a mechanism to perform additional static initialization during class definition evaluation.

ES2022 feature: class static initialization blocks
Before bashing a new feature make sure to read then criticize the actual proposal [1]. I personally think the proposal makes sense mostly because of private fields since it is very awkward to initialize those fields outside of the class.

TypeScript 4.4: The Good, The Bad and The Not So Bad
It’s an upcoming ECMAScript feature that’s currently a stage 3 proposal. static blocks allow for a more complex initiation process of static class members.

Stop using Array[index], use Array.at() instead
If you want to learn more, check out the MDN reference for it. You can also read the original proposal for it.
- ECMAScript 2022 introduces at() method in Array, String, TypedArray
-
Learning the new `at()` function, at #jslang
Just like every other array method, it’s type coerced. It’s a problem with all built ins, best not fracture this more in JS without a very good reason. https://github.com/tc39/proposal-relative-indexing-method/issues/40

Javascript ES2021 Summary
For a proposal to be finalized, it needs "Two compatible implementations which pass the acceptance tests" (source). This can mean browsers but also includes transpilers like babel. Chrome - which also includes other browsers now like Edge and Opera - will often release stage 3 features publicly before finalized, and Firefox isn't usually far behind, or sometimes even first, as was the case with the currently stage 3 at() method for arrays. Safari is probably the one you have to worry about the most. They tend to be further behind, I think mostly due to their release cadence being longer. Safari, for example, doesn't yet support private methods whereas the other browsers have supported them for some time now. While private methods are stage 4, they are expected to be part of ES2022 which hasn't been published yet - the current being ES2021.
