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.

Deciphering Error Messages and Performance Leaks

Of course, no good language is complete without a means to detect and diagnose problems in your code. JavaScript provides rich error messages that are incredibly powerful and intuitive, but there are a few caveats and tips as you tiptoe through bug-ridden code.

As you probably know, finding a problem in your own code (a "bug") is one of the most frustrating events to occur to a developer. We pride ourselves on our code's ability to do its task, but sometimes we don't account for edge and corner cases. Additionally, error messages give us important information as we're in the process of coding by giving us important diagnostic information. Luckily, there are tools that can help us understand what's going on in our JavaScript.

Let's explore.

The following topics will be covered in this chapter:
