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:

{
  "files": ["*.test.js"],
  "env": {
      "mocha": true
  },
  "rules": {
      "func-names": "off",
      "prefer-arrow-callback": "off"
  }
}

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

$ npx mocha
$ npx mocha "src/**/*.test.js"

Bold or Italics: 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."
