In Part 1, we introduced JavaScript’s Tuples and Records, highlighting their role as immutable data structures that bring predictability, performance, and safety into everyday development. In Part 2, we explored migration strategies, covering how to transition existing codebases, reduce reliance on third-party libraries, and adopt Tuples and Records incrementally.
Now, in Part 3, we’ll look beyond today’s capabilities and explore what’s on the horizon. While Tuples and Records already provide strong foundations, their current feature set is intentionally minimal. To make them even more useful in real-world applications, the JavaScript community is actively discussing potential ECMAScript proposals and speculative enhancements.
