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: "Components are real things, not just labels or placeholders, as they have built in ways to present themselves through the world via a render() function."

A block of code is set as follows:

<Box
 dimWidth={4}
 dimDepth={1}
 dimHeight={9}
 lit
/>

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

f:
mkdir f:\reactVR
cd \reactVR

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

npm install mersenne-twister --save

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: "Once you have the polygons assigned, click on View->Front then click on Mesh->UV Unwrap->Cylinder Projection."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
