The Software Supporting the JavaScript Language Specification

on YouTube ↗31m

" summary

The specification moves from a single Word document to a Git-backed web application spec that scales: ECMarkup generates the HTML, uses Egg/Gram markdown for algorithm and grammar annotations, and enforces many editorial conventions; ESMeta runs type checks in CI so many bugs are caught before PRs land. Interactive features include hoverable references, colored alias tracking, a copy-to-clipboard algorithm formatter, and propagated UC tag annotations; PDF output uses the commercial Prince tool once per year.
