I don’t see benefit in this change, let simply rewrite tests with TS

[PeterMK85]

@havenchyk
You mean to have tests in TS? I think on a longer run, it beneficial because this is actually a proper way to test. (Props has been passed with a proper type... etc)

[havenchyk]

@PeterMK85 I mean #104 currently tests are not really reliable, I started rewriting them, but it's in early state

[PeterMK85]

I would merge this and the prettier PR in, and we would have a base with the desired TS base, with the desired code formatting.

And than we can start to create FCs with test coverage.

IMHO of course

You’re a maintainer so it’s up to you. I don’t see benefits on migrating specs or applying code style to something that is going to be removed

[PeterMK85]

We have multiple this (like class components, spread logic, but because we don't want to do it in a single PR, we need to start somehow)
