How to outsmart time: Building futuristic JavaScript applications using Temporal
summary
Temporal reaches Stage 3 with a polyfill available and practical demos: nanosecond timestamps and nanosecond precision, calendar-aware parsing, explicit time‑zone handling via zoneDateTime, and built‑in arithmetic like duration.round and duration.total. A live invoice app proves parsing ISO strings, summing per-day durations, rounding to billing increments, and converting 1,000,000s seconds to ~277.777 hours; caveats include polyfill performance and fractional-duration parsing where object notation is safer than decimal strings.
