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 covered a lot of ground in this chapter. The power of JavaScript on both the frontend and the backend shows us that we can truly replace Python for many of our application needs. We've used a lot of React, but keep in mind that any frontend can be substituted here: Vue, Angular, and even frameworkless HTML, CSS, and JavaScript are at our disposal to create powerful web applications.

One of the things to note when using JavaScript and APIs is that there are cases when we need a middleware layer, for example, when saving files or accessing REST APIs with keys. Combining Express for powerful routing with a basic Node.js script to interact with an API is just the beginning of what we can accomplish with JavaScript and Node.js tied together.

In the next chapter, we'll explore webpack, a utility that allows us to logically combine and package our JavaScript application for deployment.
