Technical requirements
To develop in JavaScript, and write and then run the programs in this book, you will need the following:
- A text editor for computer programs, for example, Notepad++, Sublime Text, EditPlus, or Visual Studio.
- An internet browser, for example, Chrome, Firefox, Safari, or Edge.
- A PHP server, for example, XAMPP or WampServer. The PHP server will be used to execute JavaScript programs containing
importstatements in HTML pages because theseimportstatements only work on an HTTP server. - A Node.js server: The Node.js server will be created through Node.js installation. We will also install and use the MongoDB database to associate the Node.js server with a database.
- You can find the code files for this chapter on GitHub at: https://github.com/PacktPublishing/JavaScript-from-Frontend-to-Backend/blob/main/Chapter%201.zip.
Let’s now begin our discovery of JavaScript, by studying the different types of variables it offers us.
