Hands-on JavaScript for Python Developers

The Entrance of JavaScript into Mainstream Programming

JavaScript can run both client- and server-side, which inherently means that the use cases for using JavaScript versus Python will vary. From humble beginnings, JavaScript, with its quirks, strengths, and limitations, is now one of the main pillars of the interactive web as we know it, from powering rich frontend interactions, to web servers. How did it become one of the most important ubiquitous technologies of the web? In order to grasp JavaScript's powerful ability to add functionality to both the front- and backends, we first need an understanding of what the frontend is—and what it isn't. Having an understanding of JavaScript's origins helps to clarify the "why" of JavaScript, so let's take a look.

The following topics will be covered in this chapter:

  • The National Center for Supercomputing Applications (NCSA) and the need for interactivity
  • Early web browsers and a 10-day prototype
  • Enter Ecma International
  • HTML, CSS, and JavaScript—the best friends of the frontend
  • How JavaScript fits into the frontend ecosystem

Description

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.

Who is this book for?

This book is for experienced Python programmers who are looking to expand their knowledge of frontend and backend web development with JavaScript. An understanding of data types, functions, and scope is necessary to get to grips with the concepts covered in the book. Familiarity with HTML and CSS, Document Object Model (DOM), and Flask or Django will help you to learn JavaScript easily.

Hands-on JavaScript for Python Developers provides exactly what the title implies; if you’re into Python and need or want to start using JavaScript, this is your book. However, there’s lot more between the covers. The author has a sense of humor (Shakespearean insults?) and keeps a light, conversational style running while delivering a broad introduction to not only JS but django, react, flask, and other packages. He also provides references to useful external resources like electronjs ensuring coverage of all of the bases needed to get up and running.Examples of DOM and event-driven API calls are included as well, so after completing the book, a Python developer should be able to successfully design a functional website using JS.To the author’s credit, he does not attempt to favor one technology over the other; while this is obviously a JS-centric work, care was definitely taken to include and acknowledge the Python side of things. All in all, this is a worthwhile read and a solid reference for the bookshelf if you fall into the title category.

First and foremost, this is an easy to read book. The commentary by the author, not only about the examples laid out in the book, but just general commentary to connect the flow of the book is great. It is especially nice for those that normally don't enjoy "technical" instruction books (think dry text book from college). The author does a great job of not getting lost in technical terms, to make the text a dry read, but maintains credibility with their knowledge by how they frame the subject matter. It is a very conversational read, as if your simply conversing with the author about the subject matter.This is definitely a good book to learn JavaScript from. I think anyone with a programming background would benefit from this book, if they are wanting to gain functional knowledge of JavaScript. I would recommend this to anyone with coding knowledge as its not as specific to Python as the title may suggest. There are some areas that do a direct comparison, but overall I wouldn't let that deter you from buying this book to expand your JS knowledge.Lastly, there is quite a few historical background information pieces throughout the book that I really enjoyed from a general knowledge stand point. The background information was really helpful in allowing me to better understand the theory behind the usages in JavaScript compared to my existing knowledge from other languages.Overall, I would recommend this book to anyone looking to learn JavaScript. This book will especially help to create a solid foundation in understanding of JavaScript and how it functions within the world of programming languages. I also wouldn't limit this book to those who know Python. Python isn't my "main" language, I spend most of my programming time in C and C++, using Python more more hobby projects because of available libraries. Not being a Python expert had little to no impact on my enjoyment and learning from this book. I have recommended this to a couple of co-workers who have wanted to get a better JS understanding.

The book is not badly written, but the wording is a little confusing in some places. That’s not a deal breaker. But the book says it lets you leverage your python knowledge for faster learning, but very rarely does the author make comparisons to python. One example: in chapter 5, he talks about scoping and closures. Instead of comparing to python’s rules for the same, he explains those concepts from scratch. I bought this book intending to quickly get up to speed with JavaScript hacking known python for a while. If that’s you too, then this isn’t the book for you. I’ll update here if I find something better.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
