Learning JavaScript Data Structures and Algorithms - Third Edition

Overview of this book

A data structure is a particular way of organizing data in a computer to utilize resources efficiently. Data structures and algorithms are the base of every solution to any programming problem. With this book, you will learn to write complex and powerful code using the latest ES 2017 features. Learning JavaScript Data Structures and Algorithms begins by covering the basics of JavaScript and introduces you to ECMAScript 2017, before gradually moving on to the most important data structures such as arrays, queues, stacks, and linked lists. You will gain in-depth knowledge of how hash tables and set data structures function as well as how trees and hash maps can be used to search files in an HD or represent a database. This book serves as a route to take you deeper into JavaScript. You’ll also get a greater understanding of why and how graphs, one of the most complex data structures, are largely used in GPS navigation systems in social networks. Toward the end of the book, you’ll discover how all the theories presented in this book can be applied to solve real-world problems while working on your own computer networks and Facebook searches.

Chapter 7. Sets

Sequential data structures such as arrays (lists), stacks, queues, and linked lists should sound familiar to you by now. In this chapter, we will cover a data structure called sets, which is also a sequential data structure that does not allow duplicated values. We will learn how to create a set data structure, add and remove values, and search for whether a value already exists. We will also learn how to perform mathematical operations such as union, intersection, and difference. Finally, we will learn how to use the native ECMAScript 2015(ES2015)Setclass.

In this chapter, we will cover:

  • Creating a Set class from scratch
  • Performing mathematical operations with a Set
  • ECMAScript 2015 native Set class
