데브허브 | DEVHUB | JavaScript KILLED Record & Tuples and Replaced Them with This!
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.
