Hands-on JavaScript for Python Developers

By: Sonyl Nagale

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.

Data and Your Friend, JSON

It's time to learn the specifics of how JavaScript deals with data internally. Most of these structures are (nearly) identical to Python, but there are differences in syntax and usage. We touched on them in Chapter 3, Nitty-Gritty Grammar, but now it's time to take a deeper dive into how we work with data and use methods and properties. Understanding how to work with data is foundational to using JavaScript, especially when doing advanced work such as working with APIs and Ajax.

The following topics will be covered in this chapter:

  • Data types – both JavaScript and Python are dynamically typed!
  • Exploring data types
  • Arrays and sets
  • Objects and JSON
  • The HTTP verbs
  • API calls from the frontend – Ajax
