JavaScript Futures—ES2018 and Beyond
summary
Covers concrete ES2017/2018 additions and their status: Object.values/Object.entries, async/await (widely usable; unwraps promises and simplifies errors), rest/spread for objects, for-await-of async iteration, Promise.finally, regex lookbehinds, and Object.getOwnPropertyDescriptors. Notes Atomics/shared memory gets disabled in browsers after Spectre/Meltdown. Explains TC39 stages 0–4, that stage 3 requires two real implementations before finalization, and points to GitHub repos, the compat matrix and Babel’s role for tracking and polyfilling features.
