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.

Front-end Guide
We recommend going through the tutorial on building a tic-tac-toe game on the React homepage to get a feel of what React is and what it does. For more in-depth learning, check out the Egghead course, Build Your First Production Quality React App. It covers some advanced concepts and real-world usages that are not covered by the React documentation. Create React App by Facebook is a tool to scaffold a React project with minimal configuration and is highly recommended to use for starting new React projects.

Using Firebase with React in Firebase Hosting
I'm developing a React app created with "create react app" (https://github.com/facebookincubator/create-react-app). It will be hosted in Firebase Hosting and I'll like to use implicit initialization as describe in documentation (https://firebase.google.com/docs/web/setup#sdk_imports_and_implicit_initialization), to deploy to multiple projects (I have a dev project and several production projects)

To Review or Not to Review: The Debate on Mandatory Code Reviews
Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.

Git Project Configuration With Husky and ESLint
Let’s walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.
