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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We will create src/app/about.component.ts as a simple component that does not have any interactions."

Folder names, filenames, file extensions, pathnames, include file names in text are shown as follows: "To remove an element from an array, use the unset function."

A block of code is set as follows:

// x.ts
import { one, add, Lorem } from './y';
console.log(add(one, 2));

var lorem = new Lorem();
console.log(lorem.name);

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: "So, when we click on the Submit button, the data will be submitted."

Important new programming terms are shown in bold. Conceptual terms are shown in italics.
