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.

JavaScript Model-View-* patterns


Model-View-Controller (MVC), Model-View-Presenter (MVP), and Model-View-ViewModel (MVVM) have been popular with server applications, but in recent years JavaScript applications are also using these patterns to structure and manage large projects. Many JavaScript frameworks have emerged that support MV* patterns. We will discuss a few examples using Backbone.js.

Model-View-Controller

MVC is a popular structural pattern where the idea is to divide an application into three parts so as to separate the internal representations of information from the presentation layer. MVC consists of components. The model is the application object, view is the presentation of the underlying model object, and controller handles the way in which the user interface behaves, depending on the user interactions.

Models

Models are constructs that represent data in the applications. They are agnostic of the user interface or routing logic. Changes to models are typically notified to...
