JavaScript's Biggest Update in Years (ES2027)
ES2027 is shaping up to be the biggest JavaScript release since ES2015, and Temporal, the long-awaited replacement for Date, is finally locked in. We break down all four confirmed Stage 4 features, Temporal, the using keyword, Iterator.zip and Atomics.pause, with real code examples including a flight calculation that survives a DST change. Plus the Stage 3 proposals you can already try today, like import defer and Promise.allKeyed, and the Stage 1 Signals proposal that could change how every framework handles reactivity. 🔗 Relevant Links Date Quiz: https://jsdate.wtf/ Temporal: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal Using: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/using Iterator zip: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Iterator/zip Atomics Pause: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics/pause ❤️ More about us Radically better observability stack: https://betterstack.com/ Written tutorials: https://betterstack.com/community/ Example projects: https://github.com/BetterStackHQ 📱 Socials Twitter: https://twitter.com/betterstackhq Instagram: https://www.instagram.com/betterstackhq/ TikTok: https://www.tiktok.com/@betterstack LinkedIn: https://www.linkedin.com/company/betterstack 📌 Chapters: 0 Intro 0 Temporal 2 Explicit Resource Management (using) 3 Iterator.zip 4 Atomics.pause 5 Import Defer 5 Promise.allKeyed 6 Decorators 6 Signals
