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.

The Node.js ecosystem

Most languages aren't of the paradigm: of just writing self-contained code. Independent modules of code, called packages, are widely used in software engineering and development. To think of this in another way, even a fresh web server doesn't have software on it to serve a site out of the box. You have to install a package of software, such as Apache or nginx, to even get to the "Hello World!" step of a website. Node.js is no different. It has a number of tools to make the process of getting these packages simpler, though. Let's take a look from the ground up at a basic "Hello World!" example of a server using Node.js. We'll be discussing these concepts in more detail later, so, for now, let's just go through the basic setup.

Node.js

Of course, the first thing we need is access to the language itself. There are a few methods by which you can get Node.js on your machine, including package managers, but the most straightforward...
