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.

Summary

JavaScript has a large, respected place in the modern web. From simple beginnings at NCSA, it's now an integral part of modern web applications, whether for UI, Ajax, or other needs. It has official specifications and is constantly evolving, making working with JavaScript ever more exciting. Working in concert with HTML and CSS, it can do much more than simple interactivity, and it can easily communicate with (almost) any backend system. Its purpose is to give us more than static pages—we want pages that do work. If you coded along, we made a simple Ajax application, and while right now the commands are probably nonsensical to you, you can hopefully see that JavaScript is fairly legible. We'll be taking a deep dive into JavaScript's grammar and construction later on.

We haven't spent time discussing the backend use of JavaScript yet, but don't worry—that's next.
