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.

Misty Programming Language
This is the spec for the language Douglas Crockford (author of the book "JavaScript: The Good Parts", the JSON specification[1], JSLint[2]) had explained in his famous talk: "The Next Programming Language"[3].
The "big things" in the language are the Actor model, favouring immutability and capabilities-based security.

JavaScript Is Weird
Someone should write a book about this [0] and a tool to automate checking your JavaScript code [1].

How To Secure Your JavaScript Applications
One way to achieve this is by using linting tools like ESLint or JSLint. These tools automatically analyze your code for errors, stylistic inconsistencies, and potential security vulnerabilities. By customizing the linting rules to align with coding standards and best practices, you can identify and rectify potential security issues early in the development process. Linting helps maintain a clean and secure codebase.

JavaScript import maps are now supported cross-browser
>Does this mean that in theory i could skip the build/bundling step entirely?
You can but you must write your app in something the browser understands (js not ts, css not sass etc) and use native modules. For example, here is the test harness for a custom module, written in pure html with no build step: https://github.com/javajosh/simpatico/blob/master/combine2.h.... Here is a more complex (and much older) example from Crockford: https://www.jslint.com/
And yes, the experience developing this way is quite nice!

Find ES6 features in any JS code
I came across a problem where I had to find the ES6 features used by any javascript project and other data regarding their use. When I reached out to stackoverflow, I could find only one relevant post which asks you to use linters like jshint/jshint or compilers like babel. Jslint didn't seem to report anything specific to ES6 and Babel converts all the ES6+ features to ES5 but doesn't report anything regarding which constructs were used or how many times they were used. However, Jshint reported all ES6 features used in the code along with some metadata. And, to suit my needs, I ended up writing a python script that calls Jshint on all JS files in a project and presents the features used in the project and the number of times they were used across all files. You can find the code here : jsHintRunner

The Why & How To Create A Front-End Website Testing Plan
Javascript Linting parses and checks if any syntax is violating the rule. If a violation occurs, a warning is shown explaining unexpected behavior. Use the online version for small projects: JSLint, ESLint or JSHint. For larger projects, it is recommended to use a task runner like Gulp or Grunt. Linters ensure developers are following the best practices as a result of which few bugs appear during project development.

Disambiguating Jamstack and MACH
Programmers of classical languages hate JavaScript because it's prototype-based, dynamic and weakly typed (among other complaints). It's also the number one most in-demand programming language in 2022 according to a number of independent surveys. JSLint can help you write better JavaScript and JSMin can minify your code before deployment. These tools were created by Douglas Crockford. I would recommend his books JavaScript: The Good Parts for programmers coming to JavaScript for the first time, and How JavaScript Works for experienced JavaScript programmers.

Rolldown
Doesn't Rollup already use quite a bit of rust[0]? It's actually why I had to abandon it for a project, where they didn't offer binaries for our build platform and I needed to bundle, like 2 ES6 javascript libraries so I just grabbed esbuild instead.

Build a Vite 5 backend integration with Flask
Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

11 Ways to Optimize Your Website
Besides Webpack, there are many other popular web bundlers available, such as Parcel, Esbuild, Rollup, and more. They all have their own unique features and strengths, and you should make your decision based on the needs and requirements of your specific project. Please refer to their official websites for details.

How to rewrite classes using closures in JavaScript
The optimization points are very valid and good to keep in mind, no?
See for example:
https://github.com/rollup/rollup/issues/349
The missing minification of identifiers and properties of the Vue instance in general were always bugging me in Vue 2, even when not using the class keyword.
This is a very valid consideration IMO.

Bun vs Node.js: Everything you need to know
In the Node.js ecosystem, bundling is typically handled by third-party tools rather than Node.js itself. Some of the most popular bundlers in the Node.js world include Webpack, Rollup, and Parcel, offering features like code splitting, tree shaking, and hot module replacement.

Rollup has more than 12 million weekly NPM downloads.

How to build and publish React TypeScript NPM packages with Vite
Vite (read as vit) is actually a combination of two great frontend tools - an immensely fast development server and a build command for shipping heavily optimized static assets using Rollup. Many developers have encountered the process of setting up a project using Create React App. While CRA can be useful for beginners due to its simplicity and abstraction of configuration, it has some drawbacks that outweigh its benefits, particularly its tendency to be bloated. Don't get me wrong, Vite is opinionated as well, but it's highly extensible through its Plugin API.
What are some alternatives?
ESLint - Find and fix problems in your JavaScript code.
esbuild - An extremely fast bundler for the web
prettier - Prettier is an opinionated code formatter.
vite - Next generation frontend tooling. It's fast!
JSHint - JSHint is a tool that helps to detect errors and potential problems in your JavaScript code
tsup - The simplest and fastest way to bundle your TypeScript libraries.
jsinspect - Detect copy-pasted and structurally similar code
webpack - A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
Typefont - The first open-source library that detects the font of a text in a image.
gulp - A toolkit to automate & enhance your workflow
jsfmt - For formatting, searching, and rewriting JavaScript.
