Preface
Welcome to my second JavaScript book. In the first book, I explained the basic concepts that everyone should know, and I also discussed why those features are crucial to understand. JavaScript today is one of the most popular web programming languages, and that is the reason why Im writing this book. This book is more about intermediate to advanced features, but I will also include two extra chapters for those that want to learn the basic JavaScript concepts. This book is for everyone passionate about learning JavaScript, but with that being said, I would not start covering the basics of JavaScript in the first section. If you are new to JavaScript programming or need to refresh your memory, I recommend that you skip the first three advanced chapters of this book and read chapters four and five, where I will cover the basics of JavaScript. The idea of this book is to give you in-depth knowledge of advanced features, but as a bonus, I want to give everyone an equal chance. That is why I included the basics in the later chapters. If you already know the basics, then please start from chapter one. This book will help you master this amazing web language through many examples.
The book will include longer and smaller chapters, but I promise that they will be full of theory and examples that you will enjoy.
If you are looking for extra reference material, I recommend visiting the MDN website.

Who is this book for?
This book is for:
Students
Anyone that is considering learning JavaScript for the first time
JavaScript programmers with prior programming experience
Anyone that is seeking to gain a deep understanding of the client and server-side APIs available to JavaScript
How to Get the most out of this book?
To get the most from this book, you will need the following tools if you are using a computer or tablet:
A text editor of your choice, here I will use Visual Studio Code (VsCode).
An up-to-date browser such as Google Chrome, Firefox, Edge, or Safari.
If you are using an e-reader, you can sit back and relax because I will include many examples so that you do not miss much coding. But if you to go through the examples, please use your computer.
Download the example code files
You can download the entire code by visiting my GitHub repository page using the following link:
https://github.com/RickSekuloski/rick-javascript-book2
There you will find all of the materials (code examples and exercises) that I used in this book.
Once the file is downloaded on your computer, you will need to unzip the content. Please don't open or run the code while it's inside the zipped folders/directories. Ensure that you extract the folder into your desired destination, such as the desktop.
You can Unzip the files using the following programs:

Obtain the images you will need
Once the downloaded files are extracted, you can find all of the images I use in this book in the color-images folder. If you read this on an e-reader, some images might be blurry due to compression and resizing.
Chapter 1 Strings and Regular Expressions
In this chapter, you will learn about the regular expressions and more about Strings. We will also cover the methods that we use to process the strings. As you know, the JavaScript types can be divided into two categories: primitive and non-primitive (object type). The Strings, just like Numbers and Booleans, are considered as JavaScript Primitive types. Strings are a series of characters enclosed by single or double-quotes.
This is an example of a basic string:
let playerName = Cristiano Ronaldo;
In JavaScript, the text is considered to be from a type string. The string is a sequence of Unicode characters.
Unicode
Why do we need to use Unicode characters in the first place? Let me put it simply like this: the computer machine does not understand English letters, but they do understand the sequence of characters. That is why we need to use Unicode because it will provide a list of character sets and assign each character a unique code point. Unicode is a universal character set, and it provides a unique number for every character. Unicode version 1.0 was released in 1991, and the latest up-to-date version was released in 2021, and it includes codes for 144,667 characters. That is a lot of codes, and without Unicode programming, everything we do will be very difficult.
Characters and Code points
I already mentioned that Unicode assigns a unique code point for each character. A code point is a number assigned to a single character. These numbers can range from U+0000 to U+10FFFF . As you can see, we need to use U+, a prefix that stands for Unicode, and after the plus, we have the , which stands for a hexadecimal number. And there you have it. The Unicode manages this code point and tides them with a specific character. Another important part for you to understand is that JavaScript uses UTF-16 encoding of Unicode character set. According to the ECMAScript specification, the strings are:
The String type is the set of all ordered sequences of zero or more 16-bit unsigned integer values (elements). The String type is generally used to represent textual data in a running ECMAScript program, in which case each element in the String is treated as a UTF-16 code unit value .
Before I confuse you, even more, let us go over one simple example:
In the above example, we can see that in the variable message, we have a string that consists of 5 characters. Now we always associate the strings as a sequence of visible characters because we count the letters right, numbers, or even punctuation marks, if any? This approach will work if we use simple characters known as ASCII characters and belong to the Basic Latin block.
Let us consider the following string example:
Wait, the length is 2, and I can only see one emoji but not two. What is happening here? Well, emojis are more complex characters, and the length property will give us back 2, meaning we can no longer rely on visual characters.
The JavaScript will consider this string as a sequence of two separate code units.
As I mentioned earlier, each character is assigned a special code point right, so the first example with the message variable in the background will be processed as this sequence of UTF-16 code units:
