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.

JavaScript is not single-threaded
You forgot to mention (Web)Workers. This is explicit creation, management, and communication with additional threads within JavaScript. What's more, they've been around in JavaScript longer than the V8 engine has even existed!

Speedometer 3.0: A Shared Browser Benchmark for Web Application Responsiveness
> Is it though?
In my experience it's the buggiest browser out of the big three, and is often missing basic features like e.g.:
https://caniuse.com/?search=opus
Supported in Firefox for *12 years* now, in Chrome for 10, still no support in Safari.
They only "support" Opus audio in their special snowflake '.caf' container, which is super buggy and the last time I checked no open source program could even generate Opus '.caf' files that could be played by Safari on all Apple platforms. I ended up writing a custom converter which takes a standard '.opus' file and remuxes it on-the-fly (I only store '.opus' files on my server) into Safari-compatible '.caf' files, taking special care to massage it so that it avoids all of their demuxer/decoder bugs. You shouldn't have to do this to have cross-browser high quality audio!

Streaming HTML out of order without JavaScript
Well I'll be! In my mind I had this clear picture of Firefox implementing it.
It correct, it was only Chrome: https://caniuse.com/?search=html%20import

IPissed: Apple is after web capabilities to protect close to 100B App Store Tax
https://caniuse.com/?search=web%20bluetooth
which might be great because you have the choice...
and you can use open source chromium or brave (like the jvm to run cross platform java) to run web apps seemlessly that need web bluetooth or such but use safari or firefox for personal use if you find them more secure
I mean using chromium engine as the running environment where chromium only ever runs special trusted web domains and never goes to other "malicious" web domains that may fuck up iOS as Apple claims would be still a secure choice
like you will not download spyware from Apple Store because you are an adult not because Apple can protect you there

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!).

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

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.
