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.

In this chapter, you learned a lot about the basic building blocks of a JavaScript program. Now you know the following primitive data types:

  • Number

  • String

  • Boolean

  • Undefined

  • Null

You also know quite a few operators, which are as follows:

  • Arithmetic operators: +, -, *, /, and %

  • Increment operators: ++ and -

  • Assignment operators: =, +=, -=, *=, /=, and %=

  • Special operators: typeof and delete

  • Logical operators: &&, ||, and !

  • Comparison operators: ==, ===, !=, !==, <, >, >=, and <=

  • The ternary operator: ?

Then you learned how to use arrays to store and access data, and finally you saw different ways to control the flow of your program using conditions (if...else or switch) and loops (while, do...while, for, and

This is quite a bit of information; give yourself a well-deserved pat on the back before diving into the next chapter. More fun is coming up!
