Learning JavaScript Data Structures and Algorithms - Second Edition

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 task queues


Since we are using JavaScript in this book, why not explore a little bit more how the language works?

When we open a new tab in the browser, a task queue is created. This is because only a single thread handles all the tasks for a single tab, and it is called an event loop. The browser is responsible for several tasks, such as rendering the HTML, executing JavaScript code commands, handling user interaction (user input, mouse clicks, and so on), executing and processing asynchronous requests. You can learn more about the event loop at the following link: https://goo.gl/ayF840 .

It is really nice to know that a popular and powerful language such as JavaScript uses such a basic data structure to handle internal control.
