If you are not a completely new programmer, I am sure you must have spent some amount of time debugging your or someone else's code. Debugging is almost like an art form. Every language has different methods and challenges around debugging. JavaScript has traditionally been a difficult language to debug. I have personally spent days and nights of misery trying to debug badly-written JavaScript code using alert()
functions. Fortunately, modern browsers such as Mozilla Firefox and Google Chrome have excellent developer tools to help debug JavaScript in the browser. There are IDEs like
IntelliJ WebStorm with great debugging support for JavaScript and Node.js. In this chapter, we will focus primarily on Google Chrome's built-in developer tool. Firefox also supports the Firebug extension and has excellent built-in developer tools, but as they behave more or less the same as Google Chrome's
Developer Tools (DevTools), we will discuss common debugging approaches that work...

Overview of this book
JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language. Along with HTML and CSS, it is one of the three essential technologies of World Wide Web content production, and is an open source and cross-platform technology. The majority of websites employ JavaScript, and it is well supported by all modern web browsers without plugins. However, the JavaScript landscape has changed dramatically in recent years, and you need to adapt to the new world of JavaScript that people now expect. Mastering modern JavaScript techniques and the toolchain are essential to develop web-scale applications.
Mastering JavaScript will be your companion as you master JavaScript and build innovative web applications. To begin with, you will get familiarized with the language constructs and how to make code easy to organize. You will gain a concrete understanding of variable scoping, loops, and best practices on using types and data structures, as well as the coding style and recommended code organization patterns in JavaScript. The book will also teach you how to use arrays and objects as data structures. You will graduate from intermediate-level skills to advanced techniques as you come to understand crucial language concepts and design principles. You will learn about modern libraries and tools so you can write better code.
By the end of the book, you will understand how reactive JavaScript is going to be the new paradigm.
