Explore the upcoming JavaScript features SharedArrayBuffer and Atomics in this conference talk from JSConf EU 2017. Discover how to craft complex applications using shared memory and achieve significant performance improvements by utilizing all available CPU cores for parallel computation on the same data. Learn techniques for writing safe code while using shared memory and avoiding deadlocks of web workers. Get introduced to TurboScript, a custom TypeScript-like language designed for easy parallel programming that generates efficient asm.js-like JavaScript. Witness a live demonstration of an application created using shared memory and TurboScript: a Global Illumination Ray Tracing Renderer for Three.js.
