![]() Hooks were introduced in React Native 0.59., and because Hooks are the future-facing way to write your React components, we wrote this introduction using function component examples. First off, it’s on GitHub, and invites users to submit issues and improve the code, like any good open. But since the introduction of React's Hooks API, you can add state and more to function components. DevDocs is open source and encourages the community to contribute in a variety of ways. Originally, class components were the only components that could have state. ![]() With React, you can make components using either classes or functions. (If you are a web developer, you may already have a local environment set up for mobile browser testing!) Function Components and Class Components 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 file there. Go ahead and try changing the "Try editing me!" text above to "Hello, world!" The code is live and editable, so you can play directly with it in your browser. 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. This introduction lets you get started immediately in your browser with interactive examples like this one: Where sensible, we have linked to resources and articles that go more in depth. 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. If you’re new to JavaScript or need a refresher, you can dive in or brush up at Mozilla Developer Network. To work with React Native, you will need to have an understanding of JavaScript fundamentals. The app helps you browse and search documentation for the entire huge list of programming languages available on the DevDocs. Already familiar with React? You can skip that section-or read it for a light refresher. The DevDocs app is designed to be a wrapper around DevDocs.ios user interface, and it gives you access to all of the features and tools available on the website. You can start here and read through these docs linearly like a book or you can read the specific sections you need. These docs were written for all learners, no matter their experience level or background. 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. Continue reading for an introduction to the documentation, Native Components, React, and more! This way, you can avoid any system-related technical issues.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. In addition, you can check the minimum system requirements of the emulator on the official website before installing it. If you follow the above steps correctly, you should have the DevDocs.io ready to run on your Windows PC or MAC.
