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.

Putting It All Together

At last! We can now build both the front- and backend of a website and use JavaScript on both sides! To bring it all together, let's build a small web application that uses an Express API with a React frontend and MongoDB.

For our final project, we'll use our skills to create a database-backed travelogue or travel journal, complete with photos and stories. Our approach will be to take this from an initial visual layout, all the way through to the front- and backend code. If your HTML/CSS skills aren't great, don't worry: the code is provided for you at multiple instances so you can begin working on your project where you'd like.

The following topics will be covered in this chapter:

  • The project brief
  • Scaffolding – React
  • The backend – setting up our API
  • The database – all CRUD operations
