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

JavaScript is one of the most popular programming language nowadays. It is known as the Internet language due the fact that browsers understand JavaScript natively without installing any plugins in them. JavaScript has grown so much that is no longer just a frontend language; it is also present now on the server (NodeJS) and database as well (MongoDB).

Learning data structures is very important for any technology professional. Working as a developer means that you are able to solve problems with the help of programming languages, and data structures are an indispensible piece of the solutions that we need to create to solve these problems. Choosing the wrong data structure can also impact on performance of the program we write. That is why is important to get to know different data structures and how to apply them properly.

Algorithms are the state of art of Computer Science. There are so many ways of solving the same problem, and some approaches are better than others. This is why it is also very important to know the most famous algorithms.

This book was written for beginners who want to learn data structures and algorithms, and also for those that are already familiar with data structures and algorithms but want to learn it using JavaScript.

Happy coding!
