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.

TypeScript Is Surprisingly OK for Compilers
http://kangax.github.io/compat-table/es6/
This page lists features from es6 (and newer versions linked at the top) along with compliance to the spec. First column is the current browser, second is babel+corejs polyfills.
Overall, babel gets about 70% of the way there.

Brett Slatkin: Why am I building a new functional programming language?
Case in point: Tail Call Optimization has been part of the JS spec since ES6, but remains completely unimplemented in all mainstream browsers/engines besides Safari[1]. For all but the most predictable inputs, you're pretty much forced to use loops where recursion would otherwise be preferable.
Additional case in point: async Iterables cannot be processed as a piped stream. You must use the for await construct, which is a shame considering the FP niceties that the Array type already provides for more traditional lists. Once again, you are forced to use an imperative construct unless you specifically want to defeat the purpose of using an Iterable in the first place by trying to convert it into an Array (... and potentially choking in the process, I might add!).

- [AskJS] Is there a detailed comparison chart that shows what's supported in JavaScript ES5 versus ES6?

A single developer has been maintaining core.js with little recognition or support. Almost all modern single page apps use core.js. Millions of downloads and hardly any compensation
Eventually the browsers started racing to near-full ES6 compatibility. I remember following ES6 progress in realtime with articles and with compatibility tables http://kangax.github.io/compat-table/es6/ . But many people are acting like that either didn't happen, or like it was a one and done thing (despite the ESNext naming shift to avoid the focus on numbers). So we see people just hand-waving away the importance of polyfills like in this gem:

Tell HN: Firefox Is an awesome browser right now
> https://kangax.github.io/compat-table/es6/
Oh man this was a rough one both for FF and Chrome but Chrome did perform better slightly on cursory glance.
Thanks for providing these links, they're definitely a good rule of thumb benchmarks to test new browsers

Is there any legitimate reasons for the javascript hate?
I say this as a JS user, but there is no singular JavaScript (realistically, it's not even JavaScript but instead ECMAScript). There is no one place to go that lays out all of what the language can or can't do the way PHP and Python do. The ECMAScript board makes recommendations, then the browsers and runtimes implement features of the recommendations. This site does a good job laying out which features are implemented for browsers and runtimes based on the flavor of the ECMAScript standard. This unique experience can be especially frustrating for someone learning JavaScript and coming from another language that does not have this problem.

[AskJS] Is there a JavaScript library that will test all ES features on your browser and tell you which it supports and which it doesn't?
https://kangax.github.io/compat-table/es6/ has a column for "current browser"

Companies: We can't find any good candidates!!! Also companies:
Me in the interview: "Generally, no, a variable can only be assigned one numeric value at a time. However, Javascript is famous for unpredictable behaviors in variable comparison statements, for instance [] == ![]. There's actually a whole library built around documenting this type of behavior this for comedic value, and other more serious libraries geared towards solving the problem. So it's possible that some obscure variable assignment scenario would result in that line evaluating as true, but it's not something you'd expect to encounter in the real world. This has gotten a lot better with typescript and es2022, but still something you need to watch for a bit."

“Go is hard to justify unless at massive scale”
I do see that point of view, didn't think of that, there are some aspects of go which are a bit weird if you never touched lower abstraction languages, yet once you learn what they are, you are all set and you can code in anything. go has the least amount of gotchas I have seen in any programming language. compare it with loads of the weird stuff javascript does https://github.com/denysdovhan/wtfjs and go is like heavenly lol

Learning Frontend/React is the new rat race.
Its a very poorly designed language. Its syntax and semantics are often confusing and unpredictable. There is no well defined mental model of how constructs work in this language.
