To master React, you need to have a fundamental knowledge of JavaScript and Node.js. This book is mostly targeted at web developers, and, at the time of writing, the following assumptions were made of the reader:

• The reader knows how to install the latest version of Node.js.
• The reader is an intermediate developer who can understand JavaScript ES6 syntax.
• The reader has some experience of CLI tools and Node.js syntax.

Conventions used

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

CodeInText: 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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

html, body, #map {
 height: 100%; 
 margin: 0;
 padding: 0
}

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

const name = `Carlos`
const multilineHtml = `<p>
  This is a multiline string
 </p>`
console.log(`Hi, my name is ${name}`)

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

npm install -g @babel/preset-env @babel/preset-react

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
