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.

Ask HN: Best stack for real time data intensive apps
If you want to output to a browser here is the guide to achieve the best possible performance according to the numbers:
https://github.com/prettydiff/wisdom/blob/master/performance...
Warning: every time I post this people claim to want superior performance but then whine when they realize they have to actually write code (as opposed to letting NPM or React or jQuery do 99% of everything).

Ask HN: What are the hidden performance tricks for JavaScript?
This was attempt to research the fastest possible approach to a JavaScript GUI in the browser.
https://github.com/prettydiff/wisdom/blob/master/performance...
The techniques mentioned are stupid fast to the fewest milliseconds, but most JavaScript developers find this incredibly unpopular.
-
Ask HN: How can I learn about performance optimization?
Measure everything and be extremely critical. Be ready to challenge common and popular held assumptions.
Here is something I wrote about extreme performance in JavaScript that is discarded by most programmers because most people that program JavaScript professionally cannot really program.

Ask HN: What are good patterns for holding state?
For simple state management here is what I do: https://github.com/prettydiff/wisdom/blob/master/state_manag...
Here is an application with an OS-like GUI making use of that concept: https://github.com/prettydiff/share-file-systems

IBM study: 40% of workers will have to reskill in the next three years due to AI
The challenge is in determining who is about to become obsolete and that is not clear. For example OOP remains the most popular and requested programming paradigm even though it has gradually slid into functional obsolescence more than a decade ago[1].
Even still legacy code will remain in use and talent to maintain legacy systems will remain in demand. My university still teaches COBOL because there still exists demand for people to maintain these legacy applications even if new applications are no longer written in that language.

TypeScript Is Surprisingly OK for Compilers
That depends on how many changes it requires. If its just a matter of don't do these 3 things and your code suddenly becomes more predictable its like being slapped with a magic wand. Everybody wins. All you have to do to ensure 100% of your code compiles in a JIT is be predictable. Predictable code is, on its face, always less confusing.
> The performance benefits are likely to be minimal
This makes me cry, but not a cry of joy or ecstasy. People guessing about performance is perhaps the most frequent anti-pattern in all programming. Please read this document, you can skip to the end but it may not make much sense if you do. https://github.com/prettydiff/wisdom/blob/master/JavaScript_...

As a self learner which courses, books, tutorials have impacted you positively?
After talking about the biggest failures I have seen through my career in learning JavaScript I watched a YouTube video about an interview with a divorce attorney. It was interesting because the behaviors I heard expressed in that video exactly aligned with behaviors I see expressed in failures to learn after large commitments of time investment in programming. It inspired me to write this: https://github.com/prettydiff/wisdom/blob/master/JavaScript_...
The most important learning for me out of this is that people are predictable and how we commit is modeled by how perceptions of rewards are attained. It also inspired me to dive deeper into self learning about behavior and economics, because people do exceptionally irrational things to avoid perceived discomfort.

Why are many of the biggest web frameworks in dynamically typed langs?
> just want to know what makes a good web framework.
Personal opinion. A framework is an architecture in a box so that you, the developer, do not have to make as many decisions. Normally when developers are asking such questions they are seeking easiness: https://github.com/prettydiff/wisdom/blob/master/Easiness.md

Software developers, especially DOM fearing front developers love using the word easy. It isn’t so much an infatuation but more like a fatal attraction obsession where obstruction means war on a very emotional level. Ironically, people are loathe to confront these feelings openly and thus cannot define the word easy with any kind of clear practical application.
So, I did the world a favor and wrote just such a definition: https://github.com/prettydiff/wisdom/blob/master/Easiness.md...

Building a Front End Framework; Reactivity, Composability with No Dependencies
Depends on the definition of simplicity. People say they want simple, but then really want easy. The most easy is always somebody doing the work for you. I got tired of hearing people mention easy when really they probably mean some combination of fearful and/or lazy, so I chose to define easiness:
https://github.com/prettydiff/wisdom/blob/master/Easiness.md
If developers really wanted simplicity or to be done with work faster they would just learn the primitives of their environment: DOM, functions, and events. Most of the frameworks have APIs that are huge, so clearly simplicity isn't what's wanted.

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?
