Hands-On Data Structures and Algorithms with JavaScript

By: Kashyap Mukkamala

Overview of this book

Data structures and algorithms are the fundamental building blocks of computer programming. They are critical to any problem, provide a complete solution, and act like reusable code. Using appropriate data structures and having a good understanding of algorithm analysis are key in JavaScript to solving crises and ensuring your application is less prone to errors. Do you want to build applications that are high-performing and fast? Are you looking for complete solutions to implement complex data structures and algorithms in a practical way? If either of these questions rings a bell, then this book is for you! You'll start by building stacks and understanding performance and memory implications. You will learn how to pick the right type of queue for the application. You will then use sets, maps, trees, and graphs to simplify complex applications. You will learn to implement different types of sorting algorithm before gradually calculating and analyzing space and time complexity. Finally, you'll increase the performance of your application using micro optimizations and memory management. By the end of the book you will have gained the skills and expertise necessary to create and employ various data structures in a way that is demanded by your project or use case.

Use cases


Before we start off with use cases, let's create a base application, that will be reused for each of the examples just like we did in Chapter 1, Building Stacks for Application State Management.

The following section is a quick recap of creating a base Angular application:

Creating an Angular application

Before moving on to the individual use cases, we will first create the Angular application which will work as the base for our examples.

Follow the given commands to get up and running with the application:

  1. Install the Angular CLI:
npm install -g @angular/cli
  1. Create a new project in the folder of your choice by running the following command:
ng new <project-name>
  1. After these two steps, you should be able to see the new project created and all the corresponding node modules installed and ready to go.
  2. To run your application, run the following command from a Terminal:
ng serve
