## Summary - Adds `Bun.JSON5.parse()` and `Bun.JSON5.stringify()` as built-in APIs - Adds `.json5` file support in the module resolver and bundler - Parser uses a scanner/parser split architecture with a labeled switch pattern (like the YAML parser) — the scanner produces typed tokens, the parser never touches source bytes directly - 430+ tests covering the official JSON5 test suite, escape sequences, numbers, comments, whitespace (including all Unicode whitespace types), unquoted/reserved-word keys, unicode identifiers, deeply nested structures, garbage input, error messages, and stringify behavior <img width="659" height="610" alt="Screenshot 2026-01-25 at 12 19 57 AM" src="https://github.com/user-attachments/assets/e300125a-f197-4cad-90ed-e867b6232a01" /> ## Test plan - [x] `bun bd test test/js/bun/json5/json5.test.ts` — 317 tests - [x] `bun bd test test/js/bun/json5/json5-test-suite.test.ts` — 113 tests from the official JSON5 test suite - [x] `bun bd test test/js/bun/resolve/json5/json5.test.js` — .json5 module resolution closes #3175 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
