The ECMAScript proposal “Shared memory and atomics” by Lars T. Hansen has reached stage 4 this week and will be part of ECMAScript 2017. JavaScript started as being executed in a single thread. Web workers brought task parallelism to JavaScript.

What’s next? For low-level parallelism, the direction is quite clear: support SIMD and GPUs as well as possible.

The introduction of promises and generators in ECMAScript presents an opportunity to dramatically improve the language-level model for writing asynchronous code in ECMAScript. A similar proposal was made with Deferred Functions during ES6 discussions.
