The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Be aware of Arrays - V8 engine advice
For debugging elements kinds to figure out a given object’s “elements kind”, get a debug build of v8 (either by building from source in debug mode or by grabbing a precompiled binary using jsvu), and run: out/x64.debug/d8 --allow-natives-syntax Note that “COW” stands for copy-on-write, which is yet another internal optimization. :))

Can you make your own JavaScript by implementing ECMAScript standard?
See jsvu.

How much JS is enough for reactjs/nodejs
There is more than one JavaScript engine besides V8 https://github.com/GoogleChromeLabs/jsvu. Frameworks are not necessary at all to master JavaScript as a whole.
-
When is it better to use NodeJs and when is it better to use C#? What advantages does one have over the other?
Node.js is not the only option for JavaScript engines. There are several, including Deno, QuickJS, et al. https://github.com/GoogleChromeLabs/jsvu.

Javascript readability vs performance: a false tradeoff
To get a better understanding of why our clever one-liner FizzBuzz solution is slower, we need to take a look at how V8 works. V8 is the Javascript engine that powers NodeJS, you can directly download a binary version of the engine either via JSVU instead of compiling locally.

Jsc: My New Best Friend
Tangentially related: jsvu seems to be the easiest way to install most JS engines on most platforms. This can be useful comparing performance or compatibility across JS runtimes without firing up emulators.

Can you make your own JavaScript by implementing ECMAScript standard?
Indeed. ECMA-262 has been implemented using JavaScript https://github.com/engine262/engine262.
-
What sorts of things would you consider to be “advanced” javascript concepts?
Node.js is not the only JavaScript runtime. JavaScript runtimes have been written using JavaScript alone, see engine262. There is also Deno, QuickJS, txiki.js, Bun, none of which use COmmonJS by default, SpiderMonkey, et al.

Ask HN: What interesting problems are you working on? ( 2022 Edition)
for an interpreted language like JS, this project is really nice https://github.com/engine262/engine262. More or less 2 parts: parser and evaluator
-
Is there a source that shows how built in js methods/functions are built?
That is a bit complex, so here's a list of JS engines: if you pick one written *in* JS, that would probably be most useful -- engine262 for example

then you might be impressed by https://github.com/engine262/engine262 as well

And so was the C compiler.

[AskJS] is there a way to quantitatively check if a number value is copied or only the pointer to that number is copied?
It's outside of what you asked for, but here's a JavaScript engine in JavaScript. Might make for some interesting bedtime reading!
