This book assumes you have a basic understanding of the JavaScript programming language. It also assumes that you'll be following along with the examples, which require a command-line terminal, a code editor, and a web browser.
The requirements for learning React Native are the same as for React development, but to run an app on a real device, you will need an Android or iOS smartphone. In order to run iOS apps in the simulator, you will need a Mac computer.
Each chapter has its own folder in the code repository, and each example runs independently of the others. Generally speaking, you can use npm install and npm start to run each example. Check the README files in each folder for more specific instructions pertaining to each specific example.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
