task.js

mp; swapped = true; } } } while (swapped); return a; } // turn the function into a worker task const bubbleSortAsync = task.wrap(bubbleSort); // this now runs in a autoscaling worker pool (first run includes worker initialization time) console.time('BubbleSort Worker'); bubbleSortAsync([9,1,2,3]).then(sortedArray => { console.timeEnd('BubbleSort Worker'); }, error => { /* this is extra credit, yes we can handle worker errors */ }); Also when dealing with large messages you can use transferables (https://developer.mozilla.org/en-US/docs/Web/API/Transferabl...). The web has really came a long way, this kind of stuff is extremely useful, for instance you could use it when processing pixel data for a 10MP image with a RGBA array of 40M. In that scenario the work can be spread across all cores, and blows away the alternate approach of just locking the UI. In that case if you were using task.js you would just chunk the work, and use a async control flow library like bluebird. // in this situation all cores would be at 100% without locking the UI let processedPixels = await Promise.map(chunks, processPixelChunkAsync);
