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!).

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.

Unison Cloud
The odd thing is unison started purely as a language. Now there's a platform.
I often find the best way to understand complex things is to dig all the way back to when they were being thought up. In this case there's a blog post from 2017 that I still find useful when thinking about Unison:
https://pchiusano.github.io/2017-01-20/why-not-haskell.html
Key quote:
Composability is destroyed at program boundaries, therefore extend these boundaries outward, until all the computational resources of civilization are joined in a single planetary-scale computer
(With the open sourcing of the language I doubt it will be one computer anymore, but it's an interesting window into the original idea)
Personally I find there's a lot to this. It's interesting that we're really, really good at composing code within a program. I can map, filter, loop and do whatever I want to nested data structures with complete type safety to my heart's content. My editor's autocompleting, docs are showing up on hover, it's easy to test, all's well.
But as soon as I want cron involved, and maybe a little state-- this is all wrecked. Also deployment gets more annoying as they talk about a lot.
So I think Unison always had to have a platform to support bringing this stuff into the language, even though they built the language first.
I'd love to hear some opinions from outside Unison about how they like using this language, tooling and hosting.
I'd like to hear this too.
Also, it would be great if there was something like https://eugenkiss.github.io/7guis/ or https://todomvc.com/ for platforms that we could use to compare Unison, AWS, etc etc. Or is there already a 7GUIs for platforms that I don't know about?

Is Software Engineering Real Engineering?
The problem with this question is that, if it's not engineering, what is it? A better question is motivated by studying the history of chemistry and its progenitor, alchemy. That is: is software development alchemy or chemistry?
Software development alchemy. Just like alchemy, software dev is not standardized, everyone has their own idiosyncratic naming systems, classifications and rules-of-thumb. Like alchemists, software engineers are often jealous of their proprietary knowledge. Just like alchemists, they admired, feared and loathed for having secret knowledge. And just like alchemists, you have to be exceedingly brilliant to work in such a chaotic field and get anything done.
What changed alchemy into chemistry, and what is the analog to that in software? Arguably the change started with notion of conservation of mass and energy, and the development of the periodic table (thanks to Lavoisier and Mendeleev, respectively). As for what that analog is for software, first we need a characterization of the field. With alchemy and chemistry both, it's essentially mixing stuff together, heating and cooling it, and seeing what happens. But what is it for software?
Software engineering is often mistaken for computer science. Computer science is a tiny subset of software engineering. In practice, almost all of computer science is encapsulated in a few, tiny standard libraries - the places where bubble-sorts and hash maps live. (This mistake is consistent, and leads to "leet code" style interview questions which are irrelevant to actual work). I'd characterize software engineering as the set of solutions to a boundary value problem[0] described as "a set of interacting screens with behaviors pleasing to humans". The current solutions to this problem have been idiosyncratically shaped by resource constraints that rapidly relaxed over time[1], and characterized by elements discovered at random by necessity: e.g. kernels, processes, files, procedures, terminals, etc. In this analysis "language" functions as a kind of "coordinate system" as in physics[2][3], within which each of these elements are described, and within which elements are combined to make new elements, which eventually yield a solution to the boundary problem (which is termed "application").
I don't particularly know what the standardization of software engineering will look like, but I'm certain that this analysis, or something similar to it, is the first steps in the right direction. Personally, I look forward to the day we can shed the considerable weight of our alchemical origins.

Compare the source code at https://todomvc.com/ to see what various frameworks bring to the table. VanillaJS is generally 2-3x as much code since you have to implement the MVC logic yourself.

How easy is ruby to learn from zero experience coding
How easy or hard to build Shopify without zero coding experience? Shopify is a big thing =) So that would be hard to build with zero coding experience. Start with a todo list, micro blog, or something small in scope that interests you. https://todomvc.com/ is interesting since it is the identical app, written in many different ways, different languages and frameworks - and you can use them as reference to see how others have built something.
