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.

We've learned in this chapter that Node.js is a full-fledged programming language, capable of doing pretty much anything backend-related. We'll get into databases with Node.js in Chapter 18, Node.js and MongoDB, but, for the meantime, we can rest assured that it can do what we'd expect from a modern programming language.

The great thing about Node.js is that its grammar and structure is regular JavaScript! A few of the terms are different, but all in all, if you can read and write JavaScript, you can read and write Node.js. As with every language, there are differences in terminology and usage, but the fact is that Node.js and JavaScript are the same language!

In the next chapter, we'll discuss Node.js and Python and where certain choices make sense for using one versus the other.
