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

While the concept of running JavaScript on a server isn't new, its popularity, stability, and features are greatly expanded with Node.js. Early on, server-side JavaScript was abandoned but came to light again in 2009 with the creation of Node.js.

Node.js reduces the context-switching mental overhead for developers by working with the same fundamental grammar on both the client and server side. The same developer can work through the whole stack rather seamlessly because there are considerable similarities between the client-side work and how to operate with Node.js on the server. Along with a difference in approach also comes a different fundamental paradigm for handling requests to the server, compared to other more traditional implementations.

JavaScript: it's not just client-side anymore!

In the next chapter, we're going to take a deep dive into the grammar of JavaScript: syntax, semantics, and best practices.
