Thanks for doing this!

As a heads up, the purpose of the Test Plan section is so that the reviewer knows what you did to validate that this change was correct. If you just brought back the lines that were there before, are you sure that these versions still work? Does ESLint pass on a newly inited project still?

FWIW, I didn't really get the purpose of it until I joined Facebook :)

@TheSavior
Thanks for the information about the Test Plan! 🤗
I've written the process I've done to verify the change.
From my understanding, there are no change in the JS file from 0.62-rc.1 to the current 0.62-stable branch, so the lint check result should be the same.

Great, thanks!
