Overview of this book

This book begins by covering basics of the JavaScript language and introducing ECMAScript 7, before gradually moving on to the current implementations of ECMAScript 6. You will gain an in-depth knowledge of how hash tables and set data structure functions, as well as how trees and hash maps can be used to search files in a HD or represent a database. This book is an accessible route deeper into JavaScript. Graphs being one of the most complex data structures you’ll encounter, we’ll also give you a better understanding of why and how graphs are largely used in GPS navigation systems in social networks. Toward the end of the book, you’ll discover how all the theories presented by this book can be applied in real-world solutions while working on your own computer networks and Facebook searches.

Preface

Chapter 6.  Sets

So far, you have learned about sequential data structures such as arrays (lists), stacks, queues, and linked lists (and their variants). In this chapter, we will cover a data structure called sets, which is also a sequential data structure that does not allow duplicated values.

In this chapter, you will learn how to create a set data structure, to add and remove values, and also to search whether a value already exists. You will learn how to perform mathematical operations such as union, intersection, and difference. You will also learn how to use the native ES6 (ECMAScript 6) Set class.
