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: "At the very top of the App.js file, we're going to add our import statement."

A block of code is set as follows:

const App = () => {
  return <div className="App">Homepage!</div>;
};

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

$ yarn add bootstrap@4 reactstrap@6.5.0

Bold: Indicates a new term, an important word, or words that you see on screen. 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."
