Thanks! There’ll be some linter changes, but also we’d need tests.

[anirudh-hegde]

I think code is correct

[ljharb]

Code can’t be correct if there’s no tests to keep it so :-)

@anirudh-hegde are you no longer interested in completing this PR?

[anirudh-hegde]

To be frank I don't know how to add tests

To this file https://github.com/airbnb/polyglot.js/blob/master/test/index.js you can add a few test cases with hindi, showing that pluralization is handled correctly.
