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.

So, you now have beautiful frontend and backend code. Great! It looks so pretty sitting there on your laptop… so what's the next step? Publishing it to the world! It sounds easy, but when we have advanced JavaScript usage, such as with React, there are a couple more steps we might want to take to ensure our code is running at peak efficiency, all dependencies are resolved, and everything is compatible with modern technologies. Additionally, download size is a major consideration, so let's explore webpack, a tool to help mitigate these concerns.

We will cover the following points in this chapter:

  • The need for bundling and modules
  • Using webpack
  • Deployment
