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 2. ECMAScript and TypeScript Overview

The JavaScript language evolves every year. Since 2015, there has been a new version released every year, which we call ECMAScript, and as JavaScript is a very powerful language, it is also used for enterprise development. One of the capabilities that really helps in this type of development (among other types of application) is typed variables, which we now have, thanks to TypeScript, a superset of JavaScript.

In this chapter, you will learn some functionalities that were introduced to JavaScript since 2015, and also the advantages of using a typed version of JavaScript in our projects. We will cover the following:

  • Introduction to ECMAScript
  • JavaScript in the browser versus in the server
  • Introduction to TypeScript
