Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The inst variable holds a reference to the original object in the reflectee property."

A block of code is set as follows:

// AssemblyLine.
class AssemblyLine {
  // List of items on line.
  List _items = [];
  
  // Add [item] to line.
  add(item) {
    _items.add(item);
  }

  // Make operation on all items in line. 
  make(operation) {
    _items.forEach((item) {
      operation(item);
    });
  }
}

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

sudo apt-get install libnss3-tools

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Expand the Web SQL tree item from the Resources tab to see the Web SQL storage data."

Note

Warnings or important notes appear in a box like this.
