reactNative

React Native is a well-known mobile application development framework that allows developers to create rich, cross-platform mobile application UI using reusable components. It's ideal for building mobile applications and supports multi-platform reusable code, pre-built components, and a rich UI. Most well-known social media platforms, such as Facebook and Instagram, have been built using React Native. 

In this course, you’ll start with a brief introduction to React Native and then cover various built-in components of React Native categorized into different categories such as basic, user interface, user interaction, and list view components. Next, you’ll learn about concepts such as application styling, navigation, Hooks, state management, and database management. You’ll find interactive quizzes and challenges throughout the course to test your understanding.

By the end of this course, you’ll be able to develop mobile applications and kickstart your journey as a React Native developer.
