TypeScript Essentials

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: "To get started, let's create a new file on the filesystem and call it HelloWorld.ts."

A block of code is set as follows:

var p = document.createElement('p');
var hello: string = "Hello";
var world: string = 2;
p.textContent = hello + " " + world;

document.body.appendChild(p);

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

tsc HelloWorld.ts
