@littledan it looks like the " Babel plugin (stage-2)" checkbox can be ticked in the README:

https://www.npmjs.com/package/@babel/plugin-proposal-nullish-coalescing-operator

The flow implementation has also been closed as finished. Check that one too?

That's good news, but I meant the checkbox here:
https://github.com/tc39/proposal-nullish-coalescing/blob/master/README.md#todo

If you're looking for a supporting syntax highlighter for VSCode: mgmcdermott.vscode-language-babel now has support for the nullish coalescing operator, and also for the optional chaining operator:

Thanks for the updates, @lehni and @fmoo, and for keeping the checklist up to date, @vjpr !

About the README's TODO list, I don't think that list accurately reflects the process. PR to fix.

Closing, since this proposal is at stage 4.
