Conventions

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

Code words in text, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "In the demos you tested in the previous steps, you've tried only the digitalWrite and analogWrite methods."

A block of code is set as follows:

socket.on('error', function (error) {
  console.log('Something went wrong!');
});

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

exports = module.exports = {};
exports.start = runAnimation;
exports.stop = stopAnimation;

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

npm install async

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: " To see all the available libraries, navigate to Sketch | Import Library... on the IDE top menu."

Note

Warnings or important notes appear in a box like this.

Tip
