This is javascript, not Java.
In JavaScript something entirely new would be invented, to solve a problem that has long been solved and is documented in 20+ year old books on common design patterns. So we can all copy-paste `{ or: [{ days: 42, months: 2, hours: "DEFAULT", minutes: "IGNORE", seconds: null, timezone: "defer-by-ip" }, { timestamp: 17749453211*1000, unit: "ms"}]` without any clue as to what we are defining.
In Java, a 6000LoC+ ecosystem of classes, abstractions, dependency-injectables and probably a new DSL would be invented so we can all say "over 4 Malaysian workdays"
