It's still getting better: new(ish) JavaScript you can use today
summary
Shows concrete, battle‑tested JavaScript features used at Subito: delete operator used to remove keys from filter objects and thereby avoid extra copying; getters and setters enforce validation and make fields read‑only at runtime so illegal states never propagate; private class fields prevent external reads and accidental mutation of internal trackers and URL-builder arrays. Each example cites where it’s applied in production code, what runtime guarantee it buys, and that these patterns are supported in modern browsers today.
