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, path names, URLs, user input, and Twitter handles are shown as follows:

A block of code is set as follows:

import { Component } from '@angular/core'; 

@Component({ 
  selector: 'hello-world-app', 
  template: '<h1>Say Hello to Angular</h1>' 
}) 
class HelloWorldAppComponent { } 

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