Your knowledge of Python is a great foundation to learn other languages for your software engineering career, while JavaScript has unique features that make it integral for not only front-end development but also for streamlining work on the back-end. From working with user interactions and ingesting data from APIs, through to creating APIs with Node.js, this book will help you learn JavaScript with hands-on exercises, code snippets, and detailed descriptions of JavaScript implementation and benefits. Starting with the basics of JavaScript, you'll cover its syntax, its use in the browser, and frameworks and libraries. Since JavaScript is also used in the back-end, you'll explore Node.js and understand how it can communicate with databases. As you advance, you'll get to grips with creating your own RESTful APIs and connecting the front-end and back-end. By the end of this JavaScript book, you will 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. What you will learn Become well-versed with the implementation of JavaScript at both the front-end and back-end Understand separation of concerns while using Python programming for server-side development Differentiate between Pythonic and JavaScript coding conventions Understand front-end tasks, including UX and UI design, form validation, front-end animations, and more Create modern interaction interfaces for a web application Explore modern web technologies and libraries for building full-stack applications Who This Book Is For This book is for experienced Python programmers who are looking to expand their knowledge of front-end and back-end web development with JavaScript. Some understanding of data types, function, and scope will be necessary to get to grips with the concepts in the book. Familiarity with HTML and CSS, the Document Object Model (DOM), and Flask and/or Django will also be useful.
