Demonstrates how to use Web Workers, transfers and SharedArrayBuffer.

Blog post

This repository accompanies this blog post on Javascript parallelism.

Content

The blog post illustrates parallelism in JavaScript using a sample application to find prime numbers. This repository contains different versions of this application.

• /main-thread contains the simplest version that is blocking the main thread
• /simple-worker contains the application using a single worker thread instead of blocking the main thread
• /dividing-worker uses multiple workers, cloning the data
• /transferring-worker is using multiple workers but transfers data rather than cloning it
• /shared-buffer-worker contains a version that uses a SharedArrayBuffer to avoid cloning or the downside of transferring data
