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.

Philosophical differences between Node.js and Python

It's common to have a main language that you know, work with, and are comfortable with. However, it's important to realize that not all programming languages are created for the same purpose. That is why it's very important to use the right tool for the job at hand. Just as you wouldn't attempt to build a house with a pocketknife, you probably wouldn't use a table saw to whittle a stick into a point for a campfire for s'mores.

If you've been in the industry for a while, you have probably heard the term stack. In technology, a stack is the architectural combination of technologies used to create a program or multiple programs in an ecosystem. In the past, applications tended to be large-scale monoliths, built in a "one application to rule them all" mindset. In today's world, the use of monoliths is decreasing in favor of multiple, smaller applications and microservices. In this manner...
