Thank you for your contribution.

I've incorporated a console.log within the watchEffect for testing purposes, as shown in the attached image.

However, using MutationObserver doesn't appear to be an effective approach. It only functions post-update and fails to execute pre-update operations.

In reality, I'm progressing with the development of these Hooks features through a different strategy that I have conceptualized. You can refer to issues #86 and #82 for more details. Once prepared, I will initiate a PR.

I saw a comment for TODO in renderWatch.ts, and I thought maybe you wanted to implement the update hook in the renderWatch.ts file, so I chose to close this PR. And, like you, I believe that MutationObserver is not a good implementation solution
