I believe, we need to run prettier on all the files at least once before we merge this. No? Also @a2937 are you on our discord chat by any chance?

Not necessarily. We could do that in a follow-up PR if we wanted.

Yes I am in the discord chat. And I can try running it for sure.

Because there are literally 210 files that get reformatted, even after I create a .prettierignore file, running prettier on the project should be held off until it can be done in a followup PR.
