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.

Using Ajax and events to populate API data

Let's put it all together. For this lab, we're going to be creating a simplified Pokémon game using PokéAPI:

Here's what our game will end up being: Go ahead and pull up the site and play around with it to see the functionality.

Please resist the temptation to look at the finished JavaScript file (for now).

Here's a screenshot of what you'll see when you access the preceding URL and start playing the game:

All of the HTML and CSS have been provided for you. You'll be working in the main.js file:

If you're not familiar with Pokémon, don't worry! The logic behind this game is basic. (If you are familiar with the games, forgive the simplified approach.)
