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 covered a lot in this chapter, from routing to controllers to models. Keep in mind that not every application follows this paradigm, but it's a good baseline with which to start your approach of backend services as they relate to the frontend.

We should remember that using express-generator can help scaffold out applications, using npm or npx. Routes and views are our front line of the application, dictating where code is routed and what is viewed by the end client (whether it's JSON or HTML). We worked with APIs to explore the inherently asynchronous behavior of APIs, and also created our own API!

In the next chapter, we will discuss what makes Express a different type of framework than Django or Flask. We'll also examine how to join our frontend and backend frameworks.
