Iterator builtins now use Number counters (
bb02120)
Iterator helper and array/iterator builtin algorithms now track counters as Number values instead of reals, with explicit 2^53 limits and updated increment semantics. This tightens the spec around large iteration counts and avoids silently diverging from Number behavior.
Add SnapToInteger for finite-only integer conversion (
ad0ccf5)
Introduces a new abstract operation for converting values to finite integers with optional bounds, rejecting NaN and infinities. Number#toString and BigInt#toString now use it for radix handling, making the range check more explicit and reusable.
Introduce “epoch nanoseconds count” (1ba69a5)
Adds a named concept and range for nanosecond-precision epoch timestamps, replacing BigInt as the stated type in several Temporal-related operations. This clarifies the model for time values and aligns the core spec vocabulary around epoch nanoseconds.
Other misc changes
- Regex annex wording and production cleanups, including optional trailing-comma simplifications and Annex B lint-prep.
- Function [[Call]]/[[Construct]] editorial alignment and a small clampedLength rename.
- IANA time zone reference/link polishing.
- Minor editorial renames and phrasing tweaks in spec algorithms.
