Web apps would run much better if heavy calculations could be
performed in the background, rather than compete with the user
interface. With this book, you'll learn how to use Web Workers to
run computationally intensive JavaScript code in a thread parallel
to the UI. Yes, multi-threaded programing is complicated, but Web
Workers provide a simple API that helps you be productive without
the complex algorithms.
If you have an intermediate to advanced understanding of
JavaScript--especially event handling and callbacks--you're ready
to tackle Web Workers with the tools in this example-driven guide.
Start creating Web Workers and understand what they can and can't
do Determine which browser versions support the API Use dedicated
Web Workers for tasks that consume a lot of CPU, such as data
parsing Explore use cases for creating inline Workers, such as
encapsulating a web app in one page Create a shared Worker to
communicate multiple web app instances to the server, and other
uses Learn best practices for debugging Web Workers Apply Web
Workers within the server-side Node environment
