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.

React and React Native

Originally created by Jordan Walke at Facebook in 2013, React has quickly evolved into one of the leading user interface libraries currently in use. In contrast with Angular, React does not seek to be a complete framework, but rather focuses on specific parts of the web workflow. Since web pages are inherently stateless (that is, no real information is transferred from page to page), SPAs aim to store certain pieces of state in JavaScript memory, enabling subsequent views to be populated with data. React is a prime example of how this type of architecture works while still not encompassing the entire framework paradigm. In MVC terminology, React deals with the view layer.

Advantages of React

Since React itself only deals with views, it relies on other libraries to round out its feature set, such as React Router and Hooks. That is, the base architecture of React is designed to be modular and have add-ons used to do other parts of the workflow. At the moment, it&apos...
