This tutorial is for all the beginners who is thinking to learn React Native. So using this tutorial you can complete your first task to install Install React Native on MAC ( MACINTOSH ) system and create your first React Native project and run that project in real iOS device or iOS emulator. Today, how to uninstall angular cli and reinstall it is our main topic. Let’s discuss about how to uninstall angular cli in ubuntu. You can understand a concept of uninstall angular cli and reinstall. I would like to share with you how to remove angular cli and reinstall.

Welcome to the very start of your React Native journey! If you're looking for environment setup instructions, they've moved to [their own section](/docs/environment-setup). Continue reading for an introduction to the documentation, Native Components, React, and more!
Many different kinds of people use React Native: from advanced iOS developers to React beginners, to people getting started programming for the first time in their career. These docs were written for all learners, no matter their experience level or background.
How to use these docs#
You can start here and read through these docs linearly like a book; or you can read the specific sections you need. Already familiar with React? You can skip that section—or read it for a light refresher.
Prerequisites#
To work with React Native, you will need to have an understanding of JavaScript fundamentals. If you’re new to JavaScript or need a refresher, you can dive in or brush up at Mozilla Developer Network.
While we do our best to assume no prior knowledge of React, Android, or iOS development, these are valuable topics of study for the aspiring React Native developer. Where sensible, we have linked to resources and articles that go more in depth.
Interactive examples#

The above is a Snack Player. It’s a handy tool created by Expo to embed and run React Native projects and share how they render in platforms like Android and iOS. The code is live and editable, so you can play directly with it in your browser. Go ahead and try changing the 'Try editing me!' text above to 'Hello, world!'
Optionally, if you want to setup a local development environment, you can follow our guide to setting up your environment on your local machine and paste the code examples into your
App.js

Function Components and Class Components#
With React, you can make components using either classes or functions. Originally, class components were the only components that could have state. https://cleverview845.weebly.com/blog/streaming-apps-for-macs. But since the introduction of React's Hooks API, you can add state and more to function components.
Hooks were introduced in React Native 0.58., and because Hooks are the future-facing way to write your React components, we wrote this introduction using function component examples. Where useful, we also cover class components under a toggle like so:
- Function Component
- Class Component

You can find more examples of class components in previous versions of this documentation.
Developer Notes#
People from many different development backgrounds are learning React Native. You may have experience with a range of technologies, from web to Android to iOS and more. We try to write for developers from all backgrounds. Sometimes we provide explanations specific to one platform or another like so: Mac catalina breaks apps.
- Android
- iOS
- Web
