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.

Nitty-Gritty Grammar

When comparing two programming languages, there are bound to be structural and grammatical differences. The good news is that both Python and JavaScript are very human-readable languages, so the context switch from Python to JavaScript and Node.js shouldn't be too taxing.

Style is a good question, though: tabs or spaces? Semicolons or not? Many stylistic questions that arise when writing in any programming languages have been answered by the dicta contained within Python's PEP-8 style guide. While JavaScript doesn't have an official style guide, don't worry—it's not the Wild West out there.

Before we can write JavaScript, we must know what it is to be able to read it and understand it. All programming languages vary from one to another, and using your Python knowledge to learn a new language will require a bit of reframing of...
