[yuki0410-dev]

Description: I suggest moving from yarn to npm.

Problem

Changes

However, changing from yarn to npm is a fairly significant change to be occurring without previous consensus on doing so.

I agree. I created the PR as a suggestion, hoping that you would be able to judge from the specific changes!

Personally, I don't see the need for it, particularly as there is a workaround that is already being used.

There are some PACKAGES that cannot be deleted due to the use of YARN. https://github.com/Hacker0x01/react-datepicker/pull/4896

I have not had any problems at all with npm.

However this decision is up to the HackerOne team.

I think you are right.

@martijnrusschen Would it be possible to merge this PR conflict if I fix it?
