# Igalia-Bloomberg R&T sync

- Implementation status
- Steps for stage 3

## Updates from yesterday's R&T meeting
- No strong reason to remove .toSpliced on TA
- We are going to propose frozen R&T wrappers in plenary
- Waiting for examples from Jordan

## Implementation status

- Working prototype is there (we wanted it before stage 3)
- Working on JIT, close to finish initial implementation
- Want to first get an internal review, then publish it
- (Dan) We should get them out _before_ the september meeting, to give them time to review before stage 3
- (Dan) Yulia should be out point of contact
- (Dan) We should work in public rather than internally, talk with Yulia about this
- (Tim) some small patches already landed
- (Ioanna) there are some wip patches on phabricator
- Try to publish our patches for the July plenary

- ICs discussion between Tim and Dan (and maybe Ioanna) to happen later today.

## Steps for stage 3

- Finish the PR to support R&T where objects are expected
- Nicolò talk with Ashley
- Same for WebIDL & structuredClone
- BB CTO signed approval to contribute to WHATWG
- Other APIs (fetch, etc) are post-MVP
- Do we need test262? It would be good, but not a requirement
- (Tim/Ioanna) We have some tests in SM (non262, jit-tests)
- (Dan) We should mention them in the next tc39 presentation, if they are complete
- (Ioanna) They are not complete, mostly examples
- (Dan) We need code coverage
- (Tim) No full coverage for the jit
- (Nicolò) I think we have good coverage for the interpreter
- (Dan) Don't highlight the lack of test262, but the presence of other tests (similar to Temporal)
- (Robin) Some test262 maintainers prefer not to have a tests PR before stage 3 (Dan disagrees)
- Status update (saying that we are ready for stage 3 in September) - 45 minutes

## Action Points (before next plenary):
- [ ] Igalia: Assess current test coverage, in order to mention it in presentation at next plenary
- [ ] Complete test coverage if needed
- [ ] Put patches on phabricator.
- [ ] Ashley/Nicolò: Conclude the missing spec PRs and open issues
- [ ] Bloomberg: Prepare presentation for next plenary.

## Other

- (change-array-by-copy) test262 PR
- Dan mentions Bloomberg Hackathons we could take part if we want to.
