@Kshitij-Katiyar @raghavaggarwal2308 it's tough to know if something was missed in a PR like this when no unit tests seem to exist that cover the changes. I'm thinking we should hold off on TS conversions until we have unit test coverage. Thoughts?

[raghavaggarwal2308]

@wiggin77 We are just adding types to the existing files and not adding any functionality, so I am not sure how unit tests will be helpful here.
If you are concerned that something is changed by mistake, we can have a QA do a high level sanity for these PRs.
Please let me know your opinion.
