ECMAScript: latest and upcoming features
summary
Timeline and process detail lead to concrete outcomes: ES2016 has only two features (Array.prototype.includes and * operator), TC39 now stages proposals individually, and several Stage‑3 items are effectively ready. Notable specifics: async functions return promises and use await, already runnable in Node behind a flag; SharedArrayBuffer plus Atomics enables shared memory with explicit atomic ops; SIMD yields up to 4x speedups* for numeric kernels. Object rest/spread, dynamic import(), and async iteration are all enumerated with implementation stories.
