Overview of this book

Knowledge of Python is a great foundation for learning other languages. This book will help you advance in your software engineering career by leveraging your Python programming skills to learn JavaScript and apply its unique features not only for frontend web development but also for streamlining work on the backend. Starting with the basics of JavaScript, you’ll cover its syntax, its use in the browser, and its frameworks and libraries. From working with user interactions and ingesting data from APIs through to creating APIs with Node.js, this book will help you get up and running with JavaScript using hands-on exercises, code snippets, and detailed descriptions of JavaScript implementation and benefits. To understand the use of JavaScript in the backend, you’ll explore Node.js and discover how it communicates with databases. As you advance, you’ll get to grips with creating your own RESTful APIs and connecting the frontend and backend for holistic full-stack development knowledge. By the end of this Python JavaScript book, you’ll have the knowledge you need to write full-fledged web applications from start to finish. You’ll have also gained hands-on experience of working through several projects, which will help you advance in your career as a JavaScript developer.

Technical requirements

To code along with the examples in this chapter, you have a few choices:

  • Code directly in the JavaScript console in your browser
  • Code in the Node command line
  • Use a web editor, such as jsfiddle.net or codepen.io

Using a web editor may be preferable as you can easily save your progress. You should familiarize yourself with bringing up the JavaScript console in the browser anyway, as we'll be using it for debugging output. This is usually in the View menu in your browser; consult your browser's documentation for how to find it if it's not immediately obvious, as some browsers require turning on Developer mode in Preferences.
