Async patterns to scale your multicore JavaScript elegantly.
summary
Claims that JavaScript scales to multiple cores using ES2017 features and no magic: implements async IIFEs that return promises and form a dependency graph, a functional semaphore exposed as a limit decorator (example: allow 2 concurrent imports), and a Web Worker cluster pool sized to virtual cores that forwards tasks and returns results as promises. Demonstrates an MP3 importer moved off the main thread, preserves original API, and the demo runs successfully with no third‑party libraries.
