Overview of this book

JavaScript is an object-oriented programming language that is used for website development. Web pages developed today currently follow a paradigm that has three clearly distinguishable parts: content (HTML), presentation (CSS), and behavior (JavaScript). JavaScript is one important pillar in this paradigm, and is responsible for the running of the web pages. This book will take your JavaScript skills to a new level of sophistication and get you prepared for your journey through professional web development. Updated for ES6, this book covers everything you will need to unleash the power of object-oriented programming in JavaScript while building professional web applications. The book begins with the basics of object-oriented programming in JavaScript and then gradually progresses to cover functions, objects, and prototypes, and how these concepts can be used to make your programs cleaner, more maintainable, faster, and compatible with other programs/libraries. By the end of the book, you will have learned how to incorporate object-oriented programming in your web development workflow to build professional JavaScript applications.

Built-in objects

Earlier in this chapter, you came across the Object() constructor function. It's returned when you create objects with the object literal notation and access their constructor property. Object() is one of the built-in constructors; there are a few others, and in the rest of this chapter you'll see all of them.

The built-in objects can be divided into three groups:

  • Data wrapper objects: These are Object, Array, Function, Boolean, Number, and String. These objects correspond to the different data types in JavaScript. There is a data wrapper object for every different value returned by typeof (discussed in Chapter 2, Primitive Data Types, Arrays, Loops, and Conditions), with the exception of undefined and null.

  • Utility objects: These are Math, Date, and RegExp, and can come in handy.

  • Error objects: These include the generic Error object as well as other more specific objects that can help your program recover its working state when something unexpected happens.

Only a handful...
