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.

JavaScript has a rich grammar and syntax, developed over years of use and refinement. Using ES6, we have a whole host of data types, methods of declaring functions, and code standards. While writing JavaScript can seem to be playing very loose and fast, there are best practices, and the fundamentals of the language are as robust as other languages. Remember that capitalization counts; don't use reserved words for variable names; use const or let to declare your variables; even though JavaScript is loosely typed, data types are important; and conditionals, loops, and functions all help structure the logic of your code.

A mastery of the grammar and syntax of JavaScript is vital to understanding how to use this robust language, so take your time familiarizing yourself with the details and intricacies. Moving forward, we will presume you have fluency in JavaScript's style as we get into more difficult material.

In the next chapter, we will get our hands dirty with data and...
