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.

Frontend frameworks are powerful tools, but they're not interchangeable. Each has its pros and cons and your use of them should not only be dictated by what's en vogue at the moment but also by the community support available, performance considerations, and longevity of the project. At the end of the day, choosing a framework is a nuanced process that requires careful thought and planning. At this point in time, React has quite the uptick in adoption, but as time goes by, all frameworks fall in and out of favor. What we've covered here only scratches the surface of each of these frameworks, so be sure to do your research before committing to one.

In the next chapter, we'll explore debugging JavaScript, because let's face it: we're going to make mistakes and we'll need to know how to fix them.
