Web Developer's Reference Guide

By: Joshua Johanan, Talha Khan, Ricardo Zea

Overview of this book

This comprehensive reference guide takes you through each topic in web development and highlights the most popular and important elements of each area. Starting with HTML, you will learn key elements and attributes and how they relate to each other. Next, you will explore CSS pseudo-classes and pseudo-elements, followed by CSS properties and functions. This will introduce you to many powerful and new selectors. You will then move on to JavaScript. This section will not just introduce functions, but will provide you with an entire reference for the language and paradigms. You will discover more about three of the most popular frameworks today—Bootstrap, which builds on CSS, jQuery which builds on JavaScript, and AngularJS, which also builds on JavaScript. Finally, you will take a walk-through Node.js, which is a server-side framework that allows you to write programs in JavaScript.

Chapter 10. JavaScript Object-Oriented Programming

JavaScript is an object-oriented programming language. In object-oriented programming (OOP) languages, we use the concept of objects rather than actions to develop applications. In the past, JavaScript had no real foundation and was just a basic language. JavaScript is not a fully OOP-based language like JAVA, C#, and other programming languages, but it still has many OOP features.

There are many features in JavaScript where code is reused. So, rather than using procedural concepts in JavaScript, we use object-oriented programming techniques. There are four basic principles of object-oriented programming.
