JavaScript KILLED Record & Tuples and Replaced Them with Composites

JavaScript's records and tuples proposal has been discontinued after reaching stage 2, replaced by the new composites feature. This video explores how composites offer an alternative approach to immutability and equality checking in JavaScript objects, bringing the language closer to Python and Clojure. Learn about the differences between these proposals, how composites work with Object.freeze, and how you can start experimenting with the composite polyfill today. 🔗 Relevant Links Records and Tuples Proposal - https://github.com/tc39/proposal-record-tuple Composites Proposal - https://github.com/tc39/proposal-composites/tree/main ❤️ 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: 00:00 - Records & Tuples Discontinued 00:29 - Objects Mutability Problem 00:47 - Intended Benefits of Records & Tuples 01:04 - Introducing Composites 01:33 - Syntax Comparison 01:49 - Alignment with Other Languages 02:03 - Using the Composite Polyfill
