Issue: #11554

What I did

  • enabled code/renderers unit tests.
  • React Profiler support.
  • added stories.

How to test

  • Is this testable with Jest or Chromatic screenshots?
  • Does this need a new example in the kitchen sink apps?
  • Does this need an update to the documentation?

If your answer is yes to any of these, please make sure to include it in your PR.

It still isn't showing the actual function. Is that the expected behavior?

Would you mind checking to see if the change related to noRefCheck is tested, and adding a test, if not. Thanks!

I didn't change svelte code, and I think they 're all falsy value, so I just ran something like update-snapshots command.

Previously we didn't enable code/renderers unit test after moved all source code into code folder, but I need run unit test for react, so I manually enabled it in this PR, but svelte unit test failed, that's why I updated all code/renders snapshots here.

I need to add a story to test it, but don't know which example under examples folder should I take cra-ts-kitchen-sink or react-ts?
