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.

Converting class based components into functional ones
You can convert the “easy” render-only class components to function components using the pure-component codemod.

Front-end Guide
Developer Experience - There are a number of tools that improves the development experience with React. React Developer Tools is a browser extension that allows you to inspect your component, view and manipulate its props and state. Hot reloading with webpack allows you to view changes to your code in your browser, without you having to refresh the browser. Front end development involves a lot of tweaking code, saving and then refreshing the browser. Hot reloading helps you by eliminating the last step. When there are library updates, Facebook provides codemod scripts to help you migrate your code to the new APIs. This makes the upgrading process relatively pain-free. Kudos to the Facebook team for their dedication in making the development experience with React great.

A new way to ship Codemods
Like most popular libraries, e.g. React, Next.js and more, which provide codemods to help move their huge user base across versions, we needed a bespoke and fairly simple CLI wrapper of jscodeshift, that would provide a means of publishing, downloading and running codemods. So we created a custom 'codemod-cli', our first piece of internal codemod infrastructure.

[AskJS] How do you release libraries updates with breaking changes?
Codemods - providing automated tooling to change old patterns to new ones can go a long way in helping drive adoption of the new version. The most notable example of doing this is react-codemod (many other examples exist)

All about Abstract Syntax Tree
Sometimes you need to migrate from one version of a library to another, for example, when React has updated to version 15.5 the PropTypes has moved to different package and the react-developers provides codemod for migration.

Modern JavaScript:Everything you missed over the last 10 years(ECMAScript 2020)
Can you point me towards examples of the usage of AST rewriting tools that are actively being used by open-source library maintainers in other ecosystems to help their consumers do upgrades in large code-bases (e.g. I can see that `clang` has AST tooling, but I don't see examples online of this being widely used: https://devblogs.microsoft.com/cppblog/exploring-clang-tooli...).
Within the JavaScript ecosystem this is quite popular (1. https://github.com/reactjs/react-codemod; 2. https://github.com/mui-org/material-ui/tree/HEAD/packages/ma... 3. https://github.com/emotion-js/emotion/tree/main/packages/esl... etc.) Teams that maintain huge codebases have tooling to safely automate their upgrades and the best library maintainers provide their consumers with these AST transformations.

Introducing Astra: A Tool for Refactoring Java Programs at Scale
Agree. I know js has a similar tool, jscodeshift. https://github.com/reactjs/react-codemod and https://github.com/cpojer/js-codemod/tree/master/transforms have some ideas for js.

I’m trying to play Shinsetsu Mahou Shoujo + but it keeps giving me an error. I’ve tried changing the folder location, and renaming the folder… I also tried English, Japanese, and even Chinese locale. Can anybody help?
There is an error in some file. Or maybe some wine shenanigans (never used it). You can try searching for the file item-possessionLimit.js and paste it into something like https://jshint.com/ to get an analysis and try to fix it. But it might give you further errors or file might be packed somewhere.

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.
