Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

export default function() {
    return React.createElement(
        Text,
        {style: {marginTop: 30}},
        'Example Text!'
    );
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

export default function App() {
  return (
      <View style={styles.container}>
        ...
      </View>
  );
}

Any command-line input or output is written as follows:

yarn test -- --coverage

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "You can now tap the Details button to navigate to the Task Details screen."
