Web Workers allows you to spawn worker threads to run computation heavy pieces of javascript asynchronously and independently from your web application and the normal javascript runtime lifecycle. In practice, you will instantiate a WebWorker from your website and communicate with it back and forth through messages.

Run any business logic you like without interrupting the user experience. Multithread is a simple wrapper that eliminates the hassle of dealing with Web Workers and transferrable objects. Run any code you'd like asynchronously, in its own thread, without interrupting the user experience.

Workers in JavaScript are for running things in parallel, everyone knows that parallelism is how you make stuff Fast these days, therefore I can write a version of map that distributes the workload over 4 workers and it will be 4 times as fast as the regular map right? Sorry to burst your bubble but no you probably can’t. While your 4 worker version is going to be faster than one with 1 or 2 workers It’s going to be a lot slower than the native map method (which in fairness is going to be much slower than doing a for loop, but that’s a whole different thing).

In recent posts and talks, I've explored how Web Workers can vastly improve the responsiveness of a web application, by moving work off the UI thread and thereby reducing DOM-blocking. In this post, I'll delve a bit more deeply into the performance characteristics of postMessage(), which is the primary interface for communicating with Web Workers.…

his plugin allows you to run code inside web workers in the browser (i.e. in background threads) and access the results easily within your ember app. This is particularly useful when you're dealing with large quantities of data, or computationally expensive algorithms within your app that would otherwise lock up the browser for a period of time.

A JavaScript library all about workers. Workers should make your life easier not harder and with communistjs launching a new worker is as simple as calling a function, and it works the same across all (modern) browsers.

Just like with Flash, JavaScript code runs by default on the UI thread, and any expensive JavaScript computation will usually affect the UI responsiveness. As you may know, at 60 fps, you have around 16ms per frame to do what you have to do (computations, rendering and other misc logic). If you exceed that budget, you will alter the frame rate and potentially make your content feel sluggish or worse, unresponsive. Web Workers are now broadly available in most browsers even on mobile and give you the power of concurrency from within JavaScript. It will allow you to move expensive computations to other threads, to permit best responsive programming, and ideally open the doors in the future to true parallelization in JavaScript. Let’s have a look at the reasons why you may be interested into leveraging Web Workers.
