- React
React is a widely used JavaScript library for building user interfaces and single-page applications. It follows a component-based architecture and uses a virtual DOM to efficiently update and render UI components
- React Native
React Native is a framework for building mobile applications using React and JavaScript. It enables developers to write once and deploy to multiple platforms, including iOS, Android, and the web, while providing a native app-like experience to users.
- Eslint
ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.
- Expo
An open-source platform for making universal native apps with React. Expo runs on Android, iOS, and the web.
