Please see Contributing to ECMAScript for the most up-to-date information on contributing proposals to this standard.
Proposals that are Stage 1 and above must be transferred to the TC39 GitHub organization for discoverability and archival purposes. To onboard a proposal that lives outside the TC39 organization:
Note that as part of the onboarding process your repository name may be normalized. Don't worry, repo redirects will continue to work as long as you never create a fork, or a new repository, with the same name - although Github Pages redirects will be broken (please update your links!).
