Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “You can do these steps yourself, or look in the three-ts folder and just run yarn install there to skip this setup.”

A block of code is set as follows:

import './style.css'
import { initThreeJsScene } from './threeCanvas'
const mainElement = document.querySelector<HTMLDivElement>('#app')
if (mainElement) {
  initThreeJsScene(mainElement)
}

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

$ git --version
git version 2.30.1 (Apple Git-130)

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “For this, we need to create a new debug configuration from the Run | Edit Configurations menu.”
