Course Description

This course dives into what web workers are and provides practical demonstrations showing how they can be used to add parallel processing capabilities to a web application. In recent years, JavaScript has risen to become one of the most important languages in modern software development. However, despite the powerful engines that run it, it is often limited by its single-threaded nature. In this course, Shifting JavaScript into High Gear with Web Workers, you will learn how to work around that constraint in web applications by using the WebWorker API to allow your application to take advantage of the full power that your customer's computers have to offer. First, you will get to see why web workers are the preferred solution for adding parallel execution paths to an application. Next, you'll get a step-by-step overview of the various aspects of working with web workers, such as defining messages and what APIs can be accessed from within a worker. Finally, you'll see how web workers

can be added to a real-world application in a way that causes the smallest disruption possible to the application's structure, while gaining the advantages inherent with workers. After finishing this course, you will be ready to implement web workers into your multi-threaded applications with minimum hassle.

What you will learn

Hi everyone. My name is Michael Van Sickle and welcome to my course, Shifting JavaScript into High Gear with Web Workers. I'm a software engineer at SitePen. JavaScript is becoming increasingly relied on in modern application development, but it started to be constrained by its single-threaded execution model. By incorporating Web Workers into an application, new levels of performance are possible. In this course, we're going to learn the basics of the Web Worker API and then explore some ways that they can be used in real world applications. Some of the major topics that we will cover include the types of web workers that exist, how to communicate with a web worker, and how to incorporate web workers into real world projects. By the end of this course, you'll know how to best use web workers in your next web application. Before beginning the course, you should be familiar with client-side JavaScript development. I hope you'll join me on this journey to learn about web workers with the Shifting JavaScript into High Gear with Web Workers course at Pluralsight.
