@bklynate Will you make another commit within this PR and run npm run format on that to see what are the changes that have introduced with this PR.

I guess it was already prompting to add semicolon.

I ran npm run format.The code was well written and contained semi-colons already. I looked at 10 files and saw no issues but the rules were still missing - good to formally enforce @Abhishek-kumar09

@Abhishek-kumar09 @maverick-27 - will this PR get merged?
